International conference on particle physics and astrophysics

The discovery of a new heavy boson with a mass near 125 GeV at CERN's LHC experiments opened new horizons at Energy Frontiers. This particle is consistent with the Higgs boson predicted by the Standard Model (SM). Despite this discovery completed the SM, major questions still remain unresolved. Search for physics beyond the SM through precision measurements of the Higgs boson properties is one of the major efforts of the CMS experiment at the LHC proton collider today. The presented results are based on the 2011 and 2012 data recorded with the CMS detector, corresponding to an integrated luminosity of 5.1 fb-1 at center-of-mass energy of 7 TeV and 19.6 fb-1 at 8 TeV. The event yields obtained by the different analyses targeting specific decay modes and production mechanisms are consistent. The consistency of the couplings and the spin-parity of the observed boson with those predicted for the SM Higgs boson is tested in various ways, and no significant deviations are found so far. Finally, the prospects for the Higgs boson properties measurement at the high-luminosity LHC with CMS will be discussed.

The combination of the measurements of the Higgs boson properties by the ATLAS detector at the LHC will be presented. The results are based on 25 fb-1 of 7 TeV and 8 TeV pp collision data collected in 2011 and 2012. First, the measurements of the spin and parity of the observed boson will be discussed. Secondly, the results for the signal strength of the Higgs boson in different production processes and different decay channels will be presented. Finally, the recent combined LHC (ATLAS+CMS) fits of the couplings to Standard Model particles will be shown, as well as limits on invisible decays. All the results indicate that the observed boson is compatible with a Standard Model CP-even Higgs boson, for all parameterization models considered.

The Canfranc Underground Laboratory in north of Spain has been in operation since 2006. The underground site has three experimental Halls and a number of facilities such as seven high purity germanium detectors for radioactivity screening, a clean room, a radon abatment system. The main research field at Canfranc is astroparticle physics. However, a feasibility study for an accelerator for nuclear astrophysics is in progress. At present at Canfranc two direct dark matter projects are in operation and a double beta decay detector under commissioning. A geodynamic facility is also present underground to monitor local and global seismic events. In the talk the characteristics of the laboratories and the existing experiments will be reviewed.

The seminar will report about the activity of the INFN Scientific Commission 2, the Commission in charge of funding astroparticlle and underground physics in Italy. The focus will be, in particular, on the activities in joint collaboration between INFN and Russia.

The Borexino experiment is running at the Laboratori del Gran Sasso in Italy since 2007. Its technical distinctive feature is the unprecedented ultralow background of the inner scintillating core, which is the basis of the outstanding achievements accumulated by the experiment. In this talk, after recalling the main features of the detector, the impressive solar data gathered so far by the experiment will be summarized, with special emphasis to the most recent and prominent result concerning the detection of the fundamental pp solar neutrino flux, which is the direct probe of the engine mechanism powering our star. Such a milestone measurement puts Borexino in the unique situation of being the only experiment able to do solar neutrino spectroscopy over the entire solar spectrum; the counterpart of this peculiar status in the oscillation interpretation of the data is the capability of Borexino alone to perform the full validation across the solar energy range of the MSW-LMA paradigm. The talk will be concluded highlighting the perspectives for the final stage of the solar program of the experiment, centered on the goal to fully complete the solar spectroscopy with the missing piece of the CNO neutrinos. If successful, such a measurement would represent the final crowning of the long quest of Borexino to unravel all the properties of the neutrinos from the Sun.

The discovery of astrophysical neutrinos has lifted a new observational window to the Universe. A new generation of detectors aims to fully opening this window. The talk will describe the corresponding IceCube results which herald a new era in neutrino astronomy. It will also give an outlook to the future detectors on the multi-cubic kilometer scale: KM3NeT in the Mediterranean Sea, GVD in Lake Baikal and IceCube-Gen2 at the South Pole.

**«Research of work stability of diamond detectors that used in SCR DDIR»** ------------------------------------------------------------------------ Influence of various factors to stability of ionizing radiation detectors installed in the cosmic ray spectrometer (SCR) based on diamond detectors of ionization radiation (DDIR) was studied in this work. Diamond detectors for SCR was made from single crystals of synthetic diamond type IIa. Diamond detectors was studied successively in three different experiments. Increased ambient temperature up to 70 Сelsius degree was the first experiment, prolonged exposure to ionizing radiation of various types and energies (check if the phenomenon of polarization) was the next experiment and changing the geometry of detectors irradiation was the last experiment. The study revealed the presence of the strong influence of the polarization effect on the work of diamond detectors for registration the ionizing particles with short mean free path (in our experiment this was the a-particles of Pu-238).

Distinctive features of the multi-anode microchannel plate photomultiplier to be used in a Cherenkov detector are discussed. The laboratory test results obtained under irradiation of the MCP-PMT photocathode by picosecond optical laser pulses with different intensities (from single photon regime to the PMT saturation conditions) are presented.

Analysis of fast timing and trigger Cherenkov detector’s design for its use in collider experiments is presented. Several specific requirements are taken into account – necessity of the radiator’s placement as close to the beampipe as possible along with the requirement of gapless (solid) radiator’s design. Characteristics of the Cherenkov detector’s laboratory prototype obtained using a pion beam at the CERN Proton Synchrotron are also presented, showing the possibility of obtaining sufficiently high geometrical efficiency along with good enough timing resolution (50 ps sigma).

Gas mixtures based on xenon, argon, krypton, oxygen with the additive were studied. Values of the gas gain, the breakdown voltage for the straight and curved straw was studied. It was shown that in order to provide a necessary stability an addition of equal 3% oxygen is required. Safe operation range for all mixtures is up to gas gain equal 5*10^4. Tests with a real Barrel module confirmed these results and shown that without oxygen detector cannot sustain irradiation even at the gas gain less than 2,5*10^4 and Barrel works with argon mix if oxygen content more than 1%. Barrel works with xenon mix without oxygen. Safety margin for argon mix near 180 V, for the krypton mix near 160 V, xenon mix varies from O2 = 0% from 100 V to 170 V for 3% of oxygen for gas gain equal 2,5*10^4.

Xenon detector based gamma-ray spectrometer for the radioactive waste sorting complex and its characteristics are described. The results of this equipment tests and their analysis are presented.

Experimental results of thermal neutron detection by xenon gamma-ray spectrometers are presented. The study was performed with two devices with sensitive volumes of 0.2 and 2 liters filled with high-pressure mixture of xenon and hydrogen without neutron-capture additives. Rates of the most intensive prompt neutron-capture gamma-ray lines were simulated in order to compare them with experimental data.

When the Standard Model is extended with extra scalar particles, they mix to form physical mass eigenstates. One of these eigenstates is associated with the recently discovered 125 GeV Higgs boson. If one of the other eigenstates is sufficiently massive, it may decay to two 125 GeV states, and thus provide significant contribution to the $pp \to hh$ cross section which in the Standard Model is as low as 40 fb for $\sqrt{s} = 14$ TeV---too low to be measured before the high-luminosity LHC upgrade. In this talk three models will be considered, the first extends the SM with an isosinglet, the second with an isotriplet, and the third with two isotriplets (the Georgi-Machacek model). The first two models have two neutral scalar particles. Bounds on the $pp \to hh$ cross section coming from electroweak precision observables (isosinglet) and custodial symmetry violation (one isotriplet) will be discussed. In the case of the isosinglet bounds allow for cross section values as high as 0.5 pb, while for the isotriplet only 20 extra fb is feasible. In the Georgi-Machacek model $pp \to hh$ cross section can reach 2 pb depending on model parameters.

Search for isobar-analog states of superheavy hydrogen isotopes 5-7H was performed among the high-excited states of helium isotopes 5-7He. The excited spectra were measured in stopped pion absorption by light nuclei. The experiment was performed at low energy pion channel of LANL with two-arm multilayer semiconductor spectrometer. The method of research is based on precise measurements of energies of charged particles emitted after pion absorption by nuclei. The important advantage of this method is the possibility of studying a wide range of excitation energies up to Ex = 40 MeV. Excited states of 5-7He were observed in three-body reaction channels on the 9Be and 10,11B nuclei. Several excited levels were found only in our measurements. 6He excited state with Ex = 27.0(8) MeV observed in 10В(pi-,pt)X channel is an isobar-analog candidate for 6H with Er ~ 5.5 MeV. 7He excited state with Ex = 24.8(4) MeV observed in 10В(pi-,pd)X, 11В(pi-,pt)X and 11В(pi-,dd)X channels is an isobar-analog candidate for 7H with Er ~ 3 MeV.

Search for rare cluster configuration in 14С nucleus was carried out in the correlation measurements of stopped pion absorption reaction π¯+ 14C → p + d + Х. For our analysis we took the data obtained in the experiment on the LANL accelerator (Los Alamos, USA) using the multilayer semiconductor spectrometer [1]. The analysis of the reaction was made via previously used method for the search of rare cluster structures in 9Be [2] and 11B [3]. The study of the 2-dimensional energy distribution of the registered particles (p, d) allowed the extraction of two-body (π¯+ 14C → p (d) + 13(12)Ве) and three-body (π¯+ 14C → p + d + 11Li) reaction mechanisms. In the three-body channel we have found the region corresponding to the pion absorption by the intranuclear 3p cluster: π¯ + 3р → p + d, in this case the residual 11Li is a ”spectator”. The momentum of 11Li in the mentioned region is about pLi ≈ 150 MeV, which is typical for the movement of an intranuclear cluster. Thus, we obtained the indication on the presence of rare exotic configuration 11Li + 3р in 14C nucleus. 1. M.G. Gornov et al., Nucl. Inst. and Meth. in Phys. Res. A. 2000. V. 446. P. 461. 2. Yu.B.

Results on the measurement of the spectra of p, d, t formed in the reaction of stopped pion absorption by atomic nuclei from the wide mass number range (6 < A < 209) are presented. Phenomenological model developed by us [1, 2] had allowed to calculate contributions of cluster absorption, preequilibrium and evaporation processes in the particle formation. A-dependences of primary particles formed in the cluster absorption process are obtained. Analytical expressions are developed that allow to describe A-dependences successfully in the investigated mass number range. 1. L.Yu.Korotkova et al. // Bull. of RAS.: Phys. 2012. V. 76. P. 446. 2.

The formation of high-multiplicity nuclear stars was observed upon irradiating nuclear track emulsions with ultrarelativistic muons [1-3]. Kinematical features studied in this exposure of nuclear track emulsions for events of the muon-induced splitting of carbon nuclei to three alpha particles are indicative of the nucleardiffraction interaction mechanism. The irradiation of track emulsions with these particles makes it possible to study concurrently the multifragmentation of nuclei under the effect of a purely electromagnetic probe. Multiphoton exchanges or transitions of virtual photons to vector mesons may serve as a fragmentation mechanism. At CERN, a track-emulsion sample was exposed to 160-GeV muons. The samples under study were placed in front of the target of the COMPASS experiment at a distance of about 25 cm from the beam axis (halo), where the intensity amounted to about 10^6 particles per centimeter squared per cycle. The track-emulsion samples 9 × 12 cm in area and about 100 μm in thickness were oriented both along and across the beam. A nine-hour irradiation in the case of the transverse orientation proved to be the most favorable for our analysis. Scanning led to finding, in irradiated track emulsions, about 300 stars containing not less than three target fragments. Seventy-two stars containing only triads of b particles stopped in the track emulsion were associated with the breakup process 12^С -> 3α. Alpha-particle ranges and spatial emission angles were determined on the basis of coordinate measurements for tracks. The alpha-particle energy was estimated on the basis of the SRIM model. Its mean value proved to be 5.3 ± 0.1 MeV (RMS = 1.3 MeV). These observations, which are of a preliminary character, indicate that a full-scale investigation of a complete muon-induced disintegration of nuclei on the basis of multilayered assemblies from thick layers of substrate-free nuclear track emulsion is highly promising. 1.

Application of the nuclear track emulsion technique (NTE) in radioactivity and nuclear fission studies is discussed. It is suggested to use a HSP-1000 automated microscope for searching for a collinear cluster tri-partition of heavy nuclei implanted in NTE. Calibrations of α-particles and ion ranges in a novel NTE are carried out. Surface exposures of NTE samples to a Cf-252 source started. Planar events containing fragments and long-range α-particles as well as fragment triples only are studied. Splittings induced by thermal neutrons are studied in boron-enriched emulsion. Use of the image recognition program "ImageJ" for obtaining characteristics of individual events and for events from the large scan area are presented.

Details of the recent measurement of the Solar pp-neutrino flux will be reported. This measurement completes the measurement of Solar neutrino fluxes from the pp-chain of reactions in Borexino experiment. The result is in agreement with the prediction of the Standard Solar Model and the MSW/LMA oscillation scenario.

Borexino is a liquid scintillator detector primary designed to observe solar neutrinos. Due to its low background level as well as its position in a nuclear free country, Italy, Borexino is also sensitive to geo-neutrinos. Borexino is leading this interdisciplinary field of neutrino geoscience by studying electron antineutrinos which are emitted from the decay of radioactive isotopes present in the crust and the mantle of the Earth. With 2056 days of data taken between December 2007 and March 2015, Borexino observed 77 antineutrino candidates. If we assume a chondritic Th/U mass ratio of 3.9, the number of geo-neutrino events is found to be $23.7_{-5.7}^{+6.5}\,(\textrm{stat})\,_{-0.6}^{+0.9}\,(\textrm{syst})$. With this measurement, Borexino alone is able to reject the null geo-neutrino signal at 5.9$\,\sigma$, to claim a geo-neutrino signal from the mantle at 98$\,\%\,\textrm{C.L.}$ and to restrict the radiogenic heat production for U and Th between 23 and 36$\,\textrm{TW}$. I will review these geo-neutrino results obtained recently with Borexino.

The detection of neutrinos emitted in the CNO reactions in the Sun is one of the ambitious goals of Borexino Phase-II. A measurement of CNO neutrinos would be a milestone in astrophysics, and would allow to solve serious issues in current solar models. A precise measurement of the rate of neutrinos from the pep reaction would allow to investigate neutrino oscillations in the MSW transition region. I will review pep and CNO solar neutrino physics, the measurement in Borexino Phase-I and the perspectives for the new phase.

The new limit on the electron lifetime is obtained from data of Borexino experiment. The expected signal from the $e\rightarrow\gamma\nu$ decay mode is 256 keV photon detected in liquid scintillator. Because of extremely low radioactive background level in Borexino detector it was possible to improve the previous measurement by two orders of magnitude.

Atmospheric neutrinos are produced in interactions of cosmic rays with atomic nuclei in the Earth’s atmosphere. Although their flux is too low for studying in Borexino, atmospheric neutrinos act as a background for other processes. This talk presents the theoretical expected yield of atmospheric neutrinos in Borexino for three neutrino detection reactions: νp-ES, νe-ES and inverse β-decay, as well as the status of Monte-Carlo simulation for other interaction channels. Calculations were performed based on the only currently known detailed model of atmospheric neutrinos flux at very low energies.

Gamma-ray bursts (GRBs) are the most energetic known events in the Universe. Though gamma-ray telescopes observe about one GRB event per day, the nature of this phenomenon is not yet tottaly understood. Many theoterical models predict emission of neutrinos of all types in a wide energy range. In this talk we review experimental searches of GRB neutrinos in MeV energy range. The searches of this kind had been performed by several experiments: SuperKamiokande, SNO and KamLAND. Also the similar study is now in progress in Borexino collaboration.

The requirements and implementations of transceivers operating at speeds up to several Gb / s and intended for use in on-board data networks are considered. It is noted the possibility of upgrading for a long time used in such networks LVDS - transceivers in order to increase the transmission speed of more than prescribed by the appropriate standard. The results of the characterization of such a pseudo-LVDS transceivers designed in CMOS technology with the norms from 250 nm to 90 nm are presented.

The aim of the present work is the creation a prototype of anticoincidence system for gamma-telescope "GAMMA-400". The detector is developed on the basis of plastic scintillator and silicon photomultipliers. This work is focuses on research of the characteristics of silicon photomultipliers SiPM company SensL, type 60000. In frame of project the assembly for measuring of the photomultiplier characteristics was created. The characteristics were determined such as the linearity, boundary of saturation, the time resolution. The final stage of work was the integration of the prototype of anticoincidence detector.

We review the Effective Field Theory (EFT) to make projections on physics beyond the Standard Model in the Higgs sector. We provide relations between the non-Standard Model couplings of the Strongly-Ineracting Light Higgs (SILH) effective Lagrangian implemented in the eHDecay package and the corresponding terms of the spin-0 Higgs Characterisation model's effective Lagrangian used with the aMC@NLO Monte Carlo generator. Constraints on BSM couplings are determined on the basis of existing experimental limits on Higgs boson width and branching ratios.

The effect of intense pulsed irradiation on the operation of the liquid xenon spectrometer was studied. The ionization chamber filled with liquid xenon was irradiated by bremsstrahlung pulses of the microtron. The pulse repetition rate was 400 Hz. The absorbed dose ranged from 10-7 to 0.1 Gy per pulse. Stable operation of the liquid xenon spectrometer in the intervals between the pulses of the accelerator shown for a long time.

This report is about a part of ILC software development. The goal of this study was to create a code, that allow us to make automated testing of ILC results. The code uses the result of generation, Mokka simulation and Marlin reconstruction of ILC events. The codes task is automated Higgs recoil mass analysis everyday and to compare Higgs recoil mass with one of the previous day result.

Online calibration of neutrino liquid scintillator detector at energies above 10 MeV is very important for study of such rare process as supernova and for correct calculation of backgrounds if spectral properties is the focus of researches. The traditional procedure implies the usage of radioactive sources with well-known spectral properties but such approach is limited by available radioactive sources, upper possible energies (~10-11 MeV) and dangerous for ultra low background environment of modern detectors. The approach we propose is based on simulation of events with controllable UV double LED pulser. The LED’s main wavelength fits the scintillator excitation wavelength. This technique allows to simulate physical events within the detector in very wide energy range from a few hundred keV to about 50 MeV. Additional studies like pile-up analysis can be performed due to double-LEDs scheme which generates two delayed signals with different adjustable amplitudes. The delay time is also adjustable parameter.

We describe the pair spectrometer of the GlueX detector at Jefferson Lab. Performance of the pair spectrometer during the first beam commissioning runs is presented.

We have reviewed the modern status of the cross section of inverse beta-decay. Our analysis consist of two parts: discussing so-called "naive" cross section and its corrections. The "naive" cross section energy dependence and the corrections energy dependence are presented.

Featuring an excellent sensitivity and spatial resolution nuclear track emulsion (NTE) maintains the position of a universal and inexpensive detector for survey and exploratory research in microcosm physics. Use of this classical technique on beams of modern accelerators and reactors turns out highly productive. In a number of important tasks the completeness of observations provided in NTE cannot be achieved for electronic detection methods. In particular, in the last decade clustering work of a whole family of light nuclei including radioactive ones was investigated in the processes of dissociation of relativistic nuclei in NTE [1, 2]. Recent data on pattern of diffractive dissociation of the $^{11}C$ and $^{10}B$ will be discussed in this context. It is already established that 144 "white" stars produced by the $^{11}C$ in NTE are distributed over the charge channels in the following way: 2He + 2H (50%), 3He (17%), $^{7}Be$ + He (13%), He + 4H (11%), B+H (5%), Li + He + H (3%), 6H (2%). The distributions of He fragments over the opening angle $\theta_{2He}$ show that $^{8}Be_{g.s}$ decays are presented in 21% 2He + 2H and 19% in the 3He events. These distributions allow one to assume a strong contribution of $^{8}Be_{2+}$ decays but it is a subject of future consideration. The $^{9}B$ nucleus can exist in $^{11}C$ as an independent virtual component or as a component of a virtual basis $^{10}B$. Measurements of the first 21 stars pointed to four decays $^{8}Be_{g.s}$, two of which originated from $^{9}B_{g.s.}$ decays. Measurements of "white" stars $^{10}B$, including identification of He and H isotopes by a multiple scattering method, are in progress now. 1. P.I. Zarubin // Lect. Notes in Phys. 2013 V.875.

The Solenoidal Tracker At RHIC (STAR) uses the Time Projection Chamber (TPC) in order to perform tracking and the particle identification. With increasing statistics, it has become critical to reduce systematic uncertainties due to TPC alignment and distortion corrections (such as space charge, which has also grown with increasing luminosity). In order to improve these corrections and monitor non-static distortions, GEM-based chambers (GMT) were installed at eight locations outside TPC at the Time-Of-Flight (TOF) radius where they will provide the maximum sensitivity to the distortions. The GMT should have resolution ~150 um in both longitudinal (drift) and transverse directions and should be aligned with regard to the TPC by ~200 um. To serve that purpose we developed the software (Cluster Finder) that searches for clusters in ADC signals of each module in both directions (longitudinal and transverse) after the pedestal subtraction and measure its positions and deviations. By using this information the alignment procedure of the modules with regard to TPC has been completed and the required resolution was achieved.

The study of the internal structure of hadrons in external electromagnetic fields is important and relevant in the context of the current experiments in JLAB, COMPASS and future experiments PANDA, CBM (FAIR). The COMPASS experiment have measured electrical polarizability. In non-central heavy ions colisions the magnetic field value in the moment of collision can reach up to $15m_\pi^2 ∼ 0.27 GeV^2$. Such a strong magnetic field can modify the properties of strongly interacting matter. We calculate the correlators of pseudoscalar and vector currents in external strong abelian magnetic in $SU(3)$ pure lattice gauge theory. From the correlation functions we obtain the ground state energies of neutral and charged mesons. The energy of the $\rho^0$ meson with zero spin projection on the axis of the field decreases, while the energies with non-zero spins increase with the field value. The energy of $\pi^0$ meson decrease as a function of magnetic field. The mass of charged $\pi^\pm$ mesons increases with the field. At small magnetic fields the behaviour of energies of charged $\rho$ mesons agree with Landau level picture, while at high fields the terms with higher powers in magnetic field come into play. There are no evidences in favour of charged vector meson condensation or tachyonic mode existence at large magnetic fields. The magnetic polarizabilities of neutral and charged mesons were found for the lattice volumes $18^4$ and $20^4$ fitting the ground state energies. The g-factor of $\rho^\pm$ is found from its' ground state energies with various spins. After chiral extrapolation we obtain the value $g = 2.4 \pm 0.2$ [2] for the lattice volume $18^4$ and lattice spacing $a = 0.115fm$. This value is compatible with experimental determination [4] and theoretical value from relativistic quark model[3]. Researching QCD in the external electromagnetic field plays an important role in understanding the structure of hadrons. 1.

The GlueX experiment was designed to search for hybrid mesons with exotic quantum numbers using a beam of linearly polarized photons incident on a liquid hydrogen target. The spectrum of these states and their mass splitting from normal mesons may yield information on confinement. The Forward Drift Chambers (FDC) are multiwire drift chambers with anode and cathode read-out designed to measure tracks of charged particles coming from hydrogen target in forward direction with angles up to 20 ̊. The FDC is providing 3-dimensional points. It is using drift timing information from the wires and analog signals from the cathodes that allow working at big rate conditions. In addition to this requirement detector has minimum amount of material in active area and periphery. Active material affects momentum resolution of the charged particles and photons reconstruction by calorimeters. The amount of material in active area of all FDC system is ~1.64% X0

Under the project Advanced European Infrastructures for Detectors at Accelerators (AIDA) Institute of Nuclear Research (INR) designed and tested Totally Active Scintillator Detector (TASD). The TASD detector consists of 50 modules of plastic scintillators. Each module is instrumented with one X and one Y plane, with 86 scintillator bars per plane. The bar width, height and length are 1.0 cm, 0.7 cm and 90 cm respectively. The distance between modules can be varied from 0 to 2.5 cm. Other components such as active detectors or passive sheets of material can be inserted in these 2.5 cm gaps if required. The full detector depth can therefore be varied from 75 cm to 200 cm and in its compact form, it is 1 m3 in volume.

Using of semiconductor detectors for spectrometry of heavy ions is known to have several methodological obstacles, which are necessary to be overcome. First of them is pulse-height defect (PHD), which is manifested in the form of apparently less energies than particles actually have. Second is plasma delay effect (PD), which prevents precise measurements (TOF technique) due to creation of plasma in detectors, which is obstructing the charge collection. We discuss the quality of HI mass reconstruction using Si PIN diodes for measuring both energy and time-of-flight. The results to be presented are based on the experimental data obtained at the accelerator IC-100 in the Flerov Laboratory of the JINR (Dubna, Russia).

This article describes the neutron detector based on a ZnS(Ag)/6LiF scintillator screen. The detector was designed for a purpose of astrophysical experiments. Light collection is performed via low-opacity polystyrene layer coupled with a PMT. The work includes numerical simulation data and experimental results obtained for MeV neutron fluxes.

The results of physical and material science and technological development of new materials of radiation photonics - nano- and microstructure of radiation-sensitive and radiation-resistant optical glass and fibers based on quartz are presented in the report. The possibility of their application in neutron diagnostics devices of nuclear power objects are considered. The option of the neutron detection based on hybrid fission chamber (with oxides 235U, 238U, 232Th) with fiber-optic output optical signal in systems of control and protection of nuclear reactors is presented. Component and construction options for the radiation-sensitive fiber and glass materials (with isotopes 10B, 6Li, Gd, ions of Nd3+, Ce3+ etc.), in which radiation resistance is achieved through the organization of areas of "drain" and annihilation of radiation-induced defects are considered.

The highly granular analogue hadron calorimeter was developed and constructed by the CALICE collaboration and intensively tested with both steel and tungsten absorbers. The active layers of the calorimeter are assembled from the scintillator tiles with the individual readout by silicon photomultipliers. The longitudinal and radial development of showers induced by hadrons in the energy range from 1 to 100 GeV were studied in unprecedented detail and compared to Geant4 simulations. The possibility to achieve the hadron energy resolution of 45%/sqrt(E) with software compensation is demonstrated.

In the COMET experiment searching for the muon-electron conversion not conserving leptonic numbers, a scintillator-strip-based veto system will be used to prohibit the COMET detector from fake signals initiated by cosmic muons. In order to verify the efficiency of the system, we have built its computer model and carried out various simulations. To tune the model, experimentally measured data are utilized. The simulations give the inefficiency of the cosmic-muon registration being below 0.0001, which meets requirements of the experiment. In addition, simulations of neutrons traversing a shield beneath the cosmic-veto system have been carried out using the Geant4 toolkit. A Geant4 application has been written with an appropriate detector design and possible spectrum of neutron's energy. Design of the shield is optimized to ensure the time loss concerned with fake veto signals caused by the neutrons from muon captures in target is tolerable. Materials of shield's layers are chosen, and optimum thicknesses of the layers are computed.

Recent results on charged charmoniumlike states at Belle are presented. A full amplitude analysis of $\bar{B}^0 \to \psi(2S) K^- \pi^+$ decays, with $\psi(2S)\to\mu^+\mu^-\text{ or }e^+e^-$, was performed to constrain the spin and parity of the $Z_c(4430)^+$. The $J^P=1^+$ hypothesis is favored over the $0^-$, $1^-$, $2^-$ and $2^+$ hypotheses at the levels of $3.4\sigma$, $3.7\sigma$, $4.7\sigma$ and $5.1\sigma$, respectively. A full amplitude analysis of $\bar{B}^0 \to J/\psi K^- \pi^+$ decays was performed. A new charged charmoniumlike state $Z_c(4200)^+$ decaying to $J/\psi \pi^+$ is observed with a significance of $6.2\sigma$. The mass and width of the $Z_c(4200)^{+}$ are $4196^{+31+17}_{-29-13}$ $MeV/c^2$ and $370^{+70+70}_{-70-132}$ MeV, respectively, the preferred assignment of the quantum numbers is $J^P=1^+$. In addition, evidence for $Z_c(4430)^+ \to J/\psi \pi^+$ is found.

In this talk the decays of B-mesons into baryons will be discussed. Large mass of B-meson makes possible the decays of the type B-->baryon anti-baryon (+mesons). Experimental observations and measurements of these decays at B-factories Belle and BaBar have stimulate the development of theoretical models in this field. So we overview the experimental results together with the current theoretical models which describe baryonic B decsys.

B-factories Belle and BaBar during its operation made not only measurements connected with B-meson decays but also numerous observation and measurements in charm physics. In particular, their results on charm baryon decays and spectroscopy have enlarged and enriched the current picture of heavy flavour hadrons. In this talk we overview current status of charm baryons and their excited states. We also discuss different theoretical interpretations of newly found states.

A possible interpretation of charged charmonium-line state Z+(4430) as purely kinematical effect is discussed. This approach allows to avoid exotic states introduction to the theory. Structures in Psi(2S)pi+ mass spectrum are described by existence of Ds(*)' resonance as hidden intermediate state. Models predictions are compared to the LHCb results.

The role of pion dynamics in the X(3872) charmonium-like state is studied in the framework of a renormalisable effective quantum field theory approach and they are found to play a substantial role in the formation of the X. Chiral extrapolation from the physical point to unphysically large pion masses is performed and the results are confronted with the lattice predictions. The proposed approach overrides the gap between the lattice calculations and the physical limit in m_pi.

A practical parametrisation for the line shapes of near threshold resonance(s) is derived in the framework of a coupled-channel model which includes an arbitrary number of elastic and inelastic channels as well as a bare pole term. The parameters have a direct relation to phenomenology and can be employed to study the nature of the near-threshold states. The resulting analytical parametrisation is therefore ideally suited to investigate the full information content provided by the measurements and to establish a link between the experimental data and their theoretical interpretation.

The physics case for the international linear collider (ILC) project is discussed in this talk. The project is proposed to be built in Japan and a final decision has to be taken in 2016 on the government level. The initial data taking with e+e- beams is planned at the center-of-mass energy of 500 GeV with following runs at 250 GeV and 350 GeV. Potential physics studies at ILC are discussed with a special attention to the measurements, which expect to have better sensitivity at ILC in respect to LHC experiments.

The seminar will report about the science case and the status of the SOX project, an experiment for the search of sterile neutrinos or other short distance effects with the Borexino detector. The experimental concept, the design of the source, the calorimetric measurements and the scientific sensitivity will be reported.

The SOX project plans to deploy a radioactive antineutrino source made from 144 Cerium at the Borexino detector. It will be produced at PA Mayak from spent nuclear fuel. This source is a key component of the experiment and issues several challenges due to requirements on activity, purity and emission flux knowledge for the scientific success of the project. Moreover handling and safety with such radioactive material has its own constraints adding to the equation. This presentation will focus on the recent developments concerning the source characterization and the actions taken to obtain a precise prediction of the source radioactive emission using 144-Ce samples.

In order to perform a resolutive measurement to clarify the neutrino anomalies and to observe possible short distance neutrino oscillations, the SOX (Short distance neutrino Oscillations with BoreXino) experiment is under construction. In the first phase, a 100 kCi 144Ce-144Pr antineutrino source will be placed under the Borexino detector at the Laboratori Nazionali del Gran Sasso, in center of Italy, and the rate measurement of the antineutrino events, observed by the very low radioactive background Borexino detector, will be compared with the high precision (<1%) activity measurement performed by two calorimeters just before the source insertion in the tunnel under the Borexino. The 144Ce source will be embedded in a 19 mm thick tungsten shield and both the calorimeters have been conceived for measuring the thermal heat, absorbed by a water flow. In the presentation the two calorimeters will be described in details, paying particular attention to the techniques adopted to minimize the heat losses and to satisfy thermal and safety constrains. The status of the construction and the preliminary results performed with a mock-up heater will be also shown.

A calorimeter is being designed and constructed to measure the thermal power and thus the activity (antineutrino-generation rate) of a Cerium source for SOX with <1% accuracy. SOX aims at discovering or refuting eV-scale sterile neutrinos by searching for short-baseline oscillations of active-to-sterile neutrinos at Borexino. This talk presents the thermal model of the calorimetric measurement: numerical simulations were used to study the impact of unknown parameters on the heat distribution and propagation inside the setup, to evaluate the performance of the thermal insulation of the device and to determine the response time of the system. Together with calculations of the uncertainties, the thermal model confirms that the design of the calorimeter should provide a 0.5% uncertainty on the power measurement.

In the last years, several neutrino oscillation experiments reported results not compatible within the 3-neutrino model, which hint at the existence of light sterile neutrinos. To test this hypothesis, the SOX (Short distance neutrino Oscillations in BoreXino) experiment will search for oscillations from active to sterile neutrinos by placing radioactive electron (anti-)neutrino sources underneath the Borexino detector. Oscillations will be observed via a reduction of the detected interaction rate of the electron(anti-)neutrinos and an oscillatory pattern as a function of the neutrino energy and travelled distance. The talk will give an overview of the project and of the expected discovery potential for a 100kCi $^{144}$Ce source. The major challenges of determining the activity and the energy distribution of the source are discussed with focus on their impact on the experimental sensitivity.

Borexino is an unsegmented neutrino detector operating at LNGS in central Italy. The experiment has shown its performances through its unprecedented accomplishments in the solar and geo-neutrino detection. These performances make it an ideal tool to accomplish a state-of-the-art experiment able to test the existence of a sterile neutrino (SOX experiment). For both the solar and the SOX analysis, a good understanding of the detector response is fundamental. Consequently, calibration campaigns with radioactive sources have been performed over the years. The calibration data are of extreme importance to develop an accurate Montecarlo code. This code is used in all the neutrino analyses. The talk will show the calibration program and the advances on the detector simulation code in view of the start of the SOX data taking.

Recently dozens of new charmonium states have been observed. Most of them are so-called “XYZ” states that do not fit with the predictions of the quark model. The nature of these exotic states is still unclear. We present new experimental results from B-factories, LHCb and BESIII experiments, discuss interpretations of charmoniumlike states and perspective charmonium study.

We discuss recent results on bottomonium(-like) states from e+e- colliders. In particular we consider measurements of total b-bbar cross section and cross sections for exclusive bottomonia + light hadrons processes in the region of the Upsilon(10860) and Upsilon(11020) resonances. We also report on the recent progress with the charged bottomonium-like states Zb(10610) and Zb(10650).

We review numerous results in *B*, charm and tau physics from the *B* Factories, obtained last decade. They provide currently strong constraints on New Physics extensions beyond the Standard Model. We discuss the physics program at Super *B* factory, a next generation asymmetric collider with 50 times the luminosity of the existing colliders, and its capability in cooperation with LHC of new insights into New Physics phenomena. We aslo review the status of the construction of the machine and detector for Super *B* factory experiment.

Some problems of Universe evolution, nucleosynthesis and cosmochronology are considered from the nuclear and elementary particles physics point of view particularly using the last results obtained by using the radioactive nuclear beams. The comparison of the processes taking place in the Universe with the mechanism of formation, decay and interaction at different energies of nuclei is carried out. The examples are given showing the capabilities of nuclear physics methods in the exploration of space objects and the Universe properties. The results of nuclear reaction investigation allow new consideration of light elements nucleosynthesis scenario.

Nuclear track emulsion (NTE) is still retaining its exceptional position as a means for studying the structure of diffractive dissociation of relativistic nuclei owing to the completeness of observation of fragment ensembles and owing to its record spatial resolution. Separation of products of fragmentation and charge-exchange reactions of accelerated stable nuclei make it possible to create beams of radioactive nuclei. A unification of the above possibilities extends the investigation of the clustering phenomena in light radioactive proton-rich nuclei. Conclusions concerning clustering features are based on the probabilities for observing of dissociation channels and on measurements of angular distributions of relativistic fragments. At the JINR Nuclotron exposures of NTE stacks of (NTE) are performed at energy above 1 A GeV to the beams of isotopes Be, B, B, C and N, including radioactive ones [1]. In general, the results confirm the hypothesis that the known features of light nuclei define the pattern of their relativistic dissociation. The probability distributions of the final configuration of fragments allow their contributions to the structure of the investigated nuclei to be evaluated. These distributions have an individual character for each of the presented nuclei appearing as their original “autograph”. The nuclei themselves are presented as superposition of light nuclei-cores, the lightest nuclei-clusters and nucleons. Recent data on pattern of diffractive dissociation of the nuclei 9C, 10C, 11C and 12N will be discussed in this context. [1] P. I. Zarubin // Lect. Notes in Phys, Springer, 875, 51(2013); arXiv:1309.4881.

Various Standard Model measurements have been performed in proton-proton collisions at a centre-of-mass energy of sqrt(s) = 7 and 8 TeV using the ATLAS detector at the Large Hadron Collider. A review of a selection of the latest results of electroweak measurements, W/Z production in association with jets, jet physics and soft QCD is given. Measurements are in general found to be well described by the Standard Model predictions. First LHC Run-2 results including measurements of the properties of minimum bias interactions and early cross section measurements involving W and Z bosons are also presented.

Portable Radiometer tritium RKB-05P created for selective control tritium in the air (in gas and vapor phase) and water (in condensate water vapor from the air or in water after distillation) and to measure the activity of other beta-emitting radionuclides in water sample. The principle of operation is based on measurement of the activity of samples previously taken from the water or air in the measuring cell with special film scintillators or in liquid scintillators vessels. The device is designed for the control of tritium in enterprises associated with the use, receipt or processing of tritium, as well as for environmental monitoring. The device can be used in the work of the personnel radiation monitoring service, health care, environmental protection and other organizations that solve similar problems monitoring of tritium in samples of air or water.

The problem of electronic and scientific equipment protection becomes more actual nowadays. Protection from low-frequency electromagnetic radiation (LF EMR) is the most complicated case of electromagnetic shielding. The results of the shielding efficiency from LF EMR by multilayer film shields based on permalloy / copper systems, depending on their internal structure, the parameters of the EMR, as well as some examples of practical application are presented.

Scintillation detectors based on Hamamatsu photomultiplier tubes (PMTs) R6233-100 and R6231-100 with diameter of photocathode 76 mm and 51 mm respectively are used in GRIS experiment, which is planned to be installed onboard the ISS, and in PING-M for Interhelioprobe mission. PMT performances significantly change under the influence of a magnetic field. Even the relatively weak geomagnetic field, which typically value is about 0.5 gauss, has an appreciable effect. PMT gain variations with photocathode diameter 76 mm may reach 10-20 % depending on spatial orientation. Therefore, it is necessary to apply magnetic shields for PMT response stability enhancement. The performances investigation of magnetic shields made of steel, permalloy and amorphous metallic alloy ribbon was carried out. Influence of the shield position relative to the PMT photocathode was studied. Based on obtained data the choice of magnetic shield was made.

In different materials for magnetic shields the maximum permeability is achieved at different values of the magnetic field. This determines the choice of material. So for protection from magnetic fields strength of 10 - 150 A/m is advisable to apply the amorphous ribbon 84KXCP. For stronger fields (more than 400 A/m) multilayer film shields based on Ni20Fe80 should be used. Using these materials allows creating an effective shield working in a wide range of magnetic field strengths.

All experimental material is based on the investigation of SiPM and MPPC at the neutron source in NPI Rez.

Svetlana Kushpil on behalf of the ALICE Collaboration. The ALICE (A Large Ion Collider Experiment) detector was constructed to study the properties of hot and dense hadronic matter formed in relativistic nuclear collisions. During the second long LHC shutdown in 2018-2019, the collaboration plans to upgrade the current vertex detector, the Inner Tracking System (ITS), in order to increase the reconstruction accuracy of secondary vertices and to lower the threshold of particle transverse momentum measurement. The upgrade strategy of ITS is based on the application of new Monolithic Active Pixel Sensors (MAPS) designed in 0.18 um CMOS technology. The 50 um thick chip consists of a single silicon die incorporating a 18 um high-resistivity silicon epitaxial layer (sensor active volume) and matrix of charge collection diodes (pixels) with readout electronics. Radiation hardness of the upgraded ITS is one of the crucial elements in the overall performance of the system. A wide set of MAPS structures with different read-out circuits was produced and is being studied by the ALICE collaboration to optimize the pixel sensor functionality. An overview of the ALICE ITS upgrade and the expected performance improvement will be presented together with selected results from thorough campaign that includes several irradiation and beam tests.

sTGC chambers are designed to operate at sLHC conditions and will be installed to the ATLAS detector during Phase-I upgrade of the ATLAS muon spectrometer. These chamber will provide precise coordinate measurements of the charged particle track and level 1 trigger for high Pt muons. It is critical for the ATLAS detector to ensure a robust operation of these chambers during entire sLHC period. A quality control procedure based on X-ray scanner is being developed. Choice of the active gas for these tests is very important because on one hand it should allow to find different types of effects on the other hand one has to be sure that found problems are essential for the detector operation in a future. Studies of the operation of the sTGC chamber prototype under X-ray irradiation with two gas mixtures (n-pentan/CO2 and CO2 ) were performed. The prototype was irradiated by X-rays with energy up to 40 KeV. Particular attention was paid to the study of “hot spots”.

A New Small Wheel (NSW) is a new innermost part of the ATLAS muon end-cap system which will be installed in the ATLAS detector during forthcoming Phase-I upgrade of the Large Hadron Collider at CERN. It consists of small-strip Thin Gap Chambers (sTGC) and Micromegas chambers which were designed to sustain large particle fluxes during Super LHC operation. In order to ensure a high production quality of NSW chambers a method which uses X-ray irradiation scanner is proposed. The scanning technique offers identification of the technological defects which are vital for the chamber operation at high particle rate before the installation to the detector.

The ATLAS experiment at the Large Hadron Collider has an ambitious program of the detector upgrade to meet an expected rise of accelerator luminosity. The first large system which supposed to be installed in 2019 is a New Small Wheel (NSW) for ATLAS muon system. In order to ensure high reliability of NSW chambers an X-ray scanning technique is developed. One of the main parts of the X-ray scanner is a special software visualization tool which would allow a fast and clear representation of scanning results and an identification of possible defects.

Gas Pixel Detector (GPD) technology offer new possibilities, which make them very attractive for application in existing and future accelerator experiments and beyond. GPD combine advantages of the Si-pixel detectors and gaseous detectors. They can be produced radiation hard and have low power consumption at relatively cheap technology.Low capacitance of the individual pixel channel allows to obtain a large signal to noise ratio. Using time projection method for GPD readout one obtains 3D track image with precise coordinate and angular information. This feature would allow to achieve performance of one GPD layer equal to a few layers of silicon detectors. Implementation of a fast readout and data processing at the front-end level allows to reconstruct a track segment in less than 1 us and to use the information for the first level trigger generation. The algorithms of data acquisition and analysis are described and the results of simulations are presented in this paper.

Neutrino mixing matrix elements were discovered one by one beginning from the solar neutrinos anomaly was found and neutrino oscillation hypothesis was proposed. At the moment all elements are known excluding several complex phases. Measuring of the last mixing element $\theta_{13}$ was realized recently with three international experiments Double Chooz, RENO and Daya Bay. The highest accuracy was achieved in Daya Bay experiment. Now this result is used in accelerator experiments for looking for CP-violating phase $\delta_{CP}$.

The RED-100 (Russian Emission Detector) is being constructed for the experiment on the first observation of elastic coherent neutrino scattering off atomic nuclei. This fundamental process was predicted several decades ago by the Standard Model of electroweak interactions but has not been discovered yet. The RED-100 is an emission two-phase xenon detector containing ~200 kg of the liquid Xe (~ 100 kg in a fiducial volume). One of the possible sites to carry out the experiment is SNS (Spallation Neutron Source) facility at Oak Ridge National Laboratory, USA. SNS is the world’s most intense pulsed source of neutrinos and unique facility for their properties studying. The energy spectrum of neutrinos produced at the SNS source extends up to ~ 50 MeV and satisfy coherence condition. These neutrinos give kinetic energies of Xe recoils up to a few tens of keV where the response of LXe is well-known from neutron calibration of dark matter detectors. The detector will be deployed in a basement under the experimental hall at a distance of ~30 meters from the SNS target. The expected signal and background (neutron and gamma) are estimated for this specific location. The detector details, current status and future plans are given.

A ton-scale liquid xenon two-phase emission detector for nuclear reactor monitoring is proposed. The detector operation is based on the elastic scattering off atomic nuclei of antineutrinos coming from the reactor. It is shown that a ton-scale detector is able to measure antineutrino flux from reactor with precision necessary for nuclear reactors safeguards needs. A specific design of the detector RED-1000 is proposed. It is based on scaling up the already built RED-100 detector. The detector uses the same technologies as for RED-100 detector, and it can be assembled with the same or similar infrastructure.

Prototype of industrial reactor antineutrino detector iDREAM is dedicated for an experiment to demonstrate the possibility of remote monitoring of PWR reactor operational modes by neutrino method in real-time in order to avoid undeclared exposure modes for nuclear fuel and unauthorized removal of isotopes. The prototype detector was started up in 2014. To test the detector elements and components of electronics distilled water has been used as a target, which enables the use of Cerenkov radiation from cosmic muons as a physical signal. Also parallel measuring of the long-term stability was done for samples of liquid organic scintillator doped with gadolinium and synthesized by different methods. The work was done with the help of specially designed test detector with the volume of about 30 liters. As a result, the sample was determined which has stable light output and the concentration of gadolinium within 120 days (the time of measurement).

The T2K (Tokai-to-Kamioka) is a long baseline neutrino experiment designed to study various parameters that rule neutrino oscillations, with an intense beam of muon neutrinos. A near detector complex (ND280) is used to constrain non-oscillated flux and hence predict the expected number of events in the far detector (Super-Kamiokande). The difference in the target material between the far (water) and near (scintillator, hydrocarbon) detectors leads to the main non-cancelling systematic uncertainty for the oscillation analysis. In order to reduce this uncertainty a new water grid and scintillator detector, WAGASCI, has been proposed. The detector will be operated at the J-PARC neutrino beamline with the main physics goal to measure the charged current neutrino cross section ratio between water and hydrocarbon with a few percent accuracy. Further physics program may include high-precision measurements of different charged current neutrino interaction channels. In the talk the concepts of the new detector will be covered together with the actual construction plan.

Perspectives for the studies of diffuse supernova neutrino background (DSNB) by modern underground detectors are reviewed. DSNB neutrino fluxes, their spectra and current experimental limits on their flux are discussed.

Modular neutron detector on the basis of composite scintillators which may be used in creation of radiation monitors with a large sensitive surface was suggested. Composite scintillators are composed of dielectric gel as a basis where granules of scintillating substance, for example, gadolinium granules containing scintillators, are introduced. Thermal neutron converter, which contains 6Li or 10B isotopes, is additionally introduced when using granules of scintillators on the basis of binary compounds of zinc and selenium, or sulfur. Characteristics of the detector with the size of the sensitive surface 100x100 cm2 are obtained by the simulation on GEANT4. They allow using it as a part of GAMMA-400 space observatory.

The possibility of using the plastic scintillators for detection nuclei with high ionizing density was studied in this report. The scintillators could have different characteristics such as attenuation length, light yield efficiency. It is also important to take into account the influence of the quenching effect on the detection of heavy nuclei. It was analyzed the method of calibration plastic scintillators by means the radioactive isotopes. For that it was carried out numerically modeling the registration α-particles with energies of several MeV to determine characteristics of the scintillator that allowed interrelating amplitude of detector output and energy deposition of a nucleus. The proposed method gives the opportunity to calibrate the plastic scintillators for particles and nuclei with energy losses from 2 MeV/g/cm$^2$ (a minimum ionizing particle) up to 10$^3$ MeV/g/cm$^2$, which corresponds to the registration of nuclei from helium to iron.

The anisotropic flow coefficients $v_n$ can provide constraints crucial for precision extraction of the specific shear viscosity eta/s, of the plasma (QGP) produced in heavy-ion collisions at RHIC. A significant recent attention has been given to theoretical studies of $v_n$ (odd and even) and the associated initial [fluctuating] eccentricities which drive $v_n$. In recent experiments, the PHENIX Collaboration has made detailed differential measurements of $v_n$ (odd and even) relative to the participant event planes $\Psi_n$ as a function of transverse momentum, centrality, collision system (Au+Au, Cu+Cu, Cu+Au, d+Au, He+Au), beam energy for different particle species. The results from these measurements will be presented and discussed.

The aim of work is development detectors for diagnostic of physical process for monitoring of radiation situation at nuclear reactors, including fast neutron reactors. Detectors for registration of radiation in gas and liquid media in wide measurement range and for identification of presence of particular isotopes- gamma sources are needed. The model of scintillator detectors using crystals LaBr3(Ce) и YAlO3(Ce) were created and experimentally investigated. The possibility of identification of the presence Kr-85, Kr-85m, Kr-88, Xe-133, Xe-135, Cs-137, Cs-134, Cs-136, Cs-138, I-131, I-133, Na-24 by proposed models was demonstrated. It was demonstrated also, that the maximum measuring level of gas medium activity with 100s measuring time will be 107bq/m3. Measurement range for liquid media volumetric activity for Cs-137 with measuring time 100s is 3,79•102 Bq/l-1,08•108 Bqк/l.

This article describes the dependencies of subsonic laminar Poiseuille’s flow in a pipe of circular cross, the equations of motion of quasi-stationary processes, that are taking place when the pressure in the gas volume flows, dependencies of change of pressure in the volume of the gas flow temperature changes. This task will be interesting for design engineers that are involved in the development of high-altitude aircraft and spacecraft, and electronic systems for high-altitude machines. The main problem for creating such devices is its pre-assembling in the earth's atmosphere and its subsequent injection to the orbit of strong vacuum. The solution of this problem is to create a methodology for calculating the drainage holes in the apparatus of the above listed types.

A new neutron detector for GAMMA-400 space observatory for e/h showers separation was suggested. The detector is composed of plastic scintillation blocks wrapped by cadmium foil, and moderator layers. Its characteristics obtained by simulation on GEANT4 with the characteristics of the boron-containing scintillation detector which was installed on the International Space Station (ISS-CREAM mission) were compared. Time allocation of neutrons absorption was obtained as a function of registration time for both neutron detectors. The detector is remarkable for high neutron detection efficiency and high time resolution.

The development of model for neutron detectors for measurements of fast neuron fluxes. The construction of detectors is based on alternating layers of silicon as detector and boron (enriched with 10B) as neutron converter located in moderator. The efficiency of fast neutron registration of detectors with one layer of boron and silicon modeled by GEANT4 is very low (approximately 4%). The investigation of possible simple technologically optimization of detectors geometry to increase efficiency is presented. It is shown the efficiency is depended on numbers of layers and their locations in the materials of detectors or moderator. The optimal location is one where the numbers of layers boron-silicon are angularly related to each other.

The design of the neutron detector based on 3He-counters for use in GAMMA-400 space observatory for e/h showers separation was suggested. Its characteristics are obtained by simulation on GEANT4 with the characteristics of the neutron detector which was installed on PAMELA spectrometer were compared. Time allocation of neutrons absorption was obtained as a function of registration time for different 3He pressures. A nomogram was plotted for miscounts identification of the detector depending on the number of neutrons crossing the detector and on its time resolution.

Software has the possibilities for acquisition of gamma-ray spectra from xenon gamma-ray detector via USB or RS-485 interfaces, directly or via TCP-IP protocol, energy calibration of gamma-ray spectra, saving of gamma-ray spectra on a disk.

The goal of the proposed experiment is to check the evidence for a possible solar influence on nuclear decay rates, and to measure any effect quantitatively. Simultaneous decay rate measurements with many identical radioactive sources would allow us to study any possible correlations between their rate changes, and thus to improve the accuracy and reliability of the measurements. Positioning the sources with various distances between them (up to 2000 km), and at different altitudes above sea level and underground, will help to determine which particles, rays and other outside influences can be responsible for nuclear decay rate changes (if they really exist).

1M.V. Glebov, 2V.A. Pershukov, 3S.A. Koloskov, 1,4E.I. Nagaev 1JSC "NIITFA", 2SC "Rosatom", 3JSC "NII", 4NRNU MEPHI Mobile road pavement control facility Specialists of the State Corporation "Rosatom" developed the conception of creating a device for road pavement control, called "Condor", a basic element, which is an X-ray densitometer that has no analogues in the world. The "Condor" additionally equipped with a variety of georadar antenna units, motion sensor, GPS. On the basis of this conception prototypes of road pavement control facility was developed.

At the last years were designed many nuclear physics methods of matter elemental analysis. Many of these methods have received a complete hardware decision and became an advantage of many industrial laboratories. Measurement methods of matter composition are based on the X-ray intensity detection from the nuclei of elements which are excited by external X-ray source. The production of characteristic x-rays involves transitions of the orbital electrons of atoms in the target material between allowed orbits, or energy states, associated with ionization of the inner atomic shells. One of this methods is X-ray fluorescence analysis, which is widespread in metallurgical and processing industries and is used to identify and measure the concentration of the elements in ores and minerals on a conveyor belt. In this work for the calibration curve construction is used coupling equation. Samples of copper ore with a known concentrations of elements, were taken from the Ural deposit. To excite the characteristic X-rays were used radionuclide sources Cd-109, with half-life 461,4 days. After finding the calibration coefficients, have been made control measurements of samples and averaging of over all samples. Measurement error did not exceed 1.1%.

In the experiments at the FOBOS spectrometer [H-G.Ortlepp, et al., NIM A 403 (1998) 65] dedicated to study of the spontaneous fission of the 248Cm and 252Cf nuclei in the mass correlation distribution of fission fragments new unusual structures bounded by magic clusters were observed for the first time. The structures were interpreted as a manifestation of a new exotic decay called collinear cluster tri-partition (CCT). These pioneer results were confirmed and detailed later in the series of experiments at different time-of-flight spectrometers [D.V. Kamanin, Yu. V. Pyatkov, "Clusters in Nuclei - Vol.3" ed. by C. Beck, Lecture Notes in Physics 875, pp. 183-246 (2013)]. Interpretation of the results obtained needs estimation of the statistical reliability of the structures mentioned above. The report presents the results of the solution of the problem of estimation of statistical reliability of linear point structures on the basis of methods of morphological image analysis [Pyt’ev Yu.P. Morphological Image Analysis. — Pattern Recognition and Image Analysis. V.3. No 1. 1993, pp. 19-28.].

The two-particle correlations at low relative momenta (also known as correlation femtoscopy) are sensitive to quantum statistics and allow to measure the space-time picture of the system evolution created in heavy-ion (HI) and particle collisions. The spatio-temporal parameters extracted from HI collisions describe the system at the last moment of the collision evolution - kinetic freeze-out and provide the essential information about the formation of the quark-gluon plasma. The measurements at many facilities showed the dependencies of the spacial scales from the event multiplicity and particle transverse mass ($m_T$). In this work we show recent results obtained at RHIC and LHC energies and compare them to the theoretical expectations.

A hot and dense matter called strongly interacting quark-gluon plasma (sQGP) is created in heavy ion collisions at RHIC energies. Detailed study of the properties of this new state of matter is a driving force of recent research at RHIC. Hard scattered partons loose energy via rescattering and radiation traversing the medium produced in heavy ion collisions resulting in suppressed production of high pT hadrons or jet quenching. Thus measurement of high pT hadron production is a way to probe opacity and density of the produced medium. At intermediate pT hadron production is defined by competing particle production mechanisms which are sensitive as to jet fragmentation and quenching as to collective effects in the produced medium. The electromagnetic probes such as direct photons are not affected by strong nuclear forces. They are extremely valuable in study of the jet quenching phenomena and in constraining the time evolution of the medium. In this talk we present recent PHENIX results for system size and energy dependence of intermediate and high pT hadron production in heavy ion collisions at RHIC. We also report latest results for direct photon production including soft direct photon yields and anisotropic flow.

The CP symmetry breaking in quantum chromodynamics (QCD) could be realized via transitions between local fluctuations of gauge fields. Azimuthal correlations which characterize the asymmetry of the emitted charged particles with respect to the reaction plane in non-central nucleus-nucleus collisions are the promising tools for experimental study of local CP violation in the strong interactions. The preliminary estimations of correlators within the model of chiral magnetic effect are presented for types of nuclei and collision energies corresponded to RHIC and the LHC beams for two various nuclear densities, namely, for approach of the hard sphere and for the two-component Fermi model. Besides of the correlator estimations for the symmetric collisions, the results for asymmetric Cu+Au collisions are also discussed.

The energy dependence of the chaoticity parameter, derived from Bose-Einstein correlations (BEC) of pion-pairs produced in proton-proton collisions, is investigated. Considered are the one and three dimensions (1D, 3D) of the BEC analyzed in terms of a Gaussian and / or exponential distributions. A marked difference is observed between the dependence of the chaoticity on energy in the 1D and the 3D analyses. The experimental data are examined in terms of the relation between the pion sources and the BEC dimension R which in turn are deduced from the charged outgoing particle multiplicity. This approach follows the 1D chaoticity general energy behavior as obtained from the BEC analyzes of the proton-proton collision data. Prediction for the chaoticity dependence on ener-gy is obtained over a multi-TeV energy range based on a model of independent pion sources. The decrease of the chaoticity value with energy is expected within the framework of this approach is supported by the experimental findings.

The expected performance of the Projectile Spectator Detector (PSD) for the CBM experiment at the future FAIR facility will be presented. The PSD is a compensating lead-scintillator calorimeter designed to measure the energy distribution of the projectile nuclei fragments (spectators) and forward going particles produced close to the beam rapidity. The main purpose of the PSD is to provide an experimental estimates of heavy-ion collision centrality and reaction (symmetry) plane orientation. A sample of heavy-ion collisions simulated with realistic modeling of nuclei fragment production, directed and elliptic flow of produced particles and transported through the GEANT Monte-Carlo of the CBM detector geometry is used to study the PSD performance. Performance of the centrality and reaction plane determination is explored with the PSD as a standalone detector and in a combination with other CBM subsystems.

The measurements of collective flow effects in particle production have provided invaluable insights on the transport properties of the strongly interacting matter produced in relativistic heavy-ion collisions at RHIC. The detailed comparison of flow measurements from PHENIX and STAR experiments at RHIC will be presented and discussed. The suggestions for the future measurements of flow at RHIC will be provided.

Azimuthal anisotropy is one of the key observables to study the properties of matter created in high energy heavy-ion collisions at RHIC and LHC. The collective behavior is quantified in terms of anisotropy coefficients $v_n$ measured with respect to their corresponding event planes. Predictions from the viscous hydrodynamics for the scaling of the anisotropic flow coefficients $v_n$ with eccentricity, system size and transverse energy are tested using the recent data from the PHENIX Collaboration.

For large volume neutrino and antineutrino detectors it is crucial to have an efficient data acquisition system capable of digitizing data from thousands of detection channels. Here we present a flexible DAQ system architecture consisting of large number of fast waveform digitizers and configurable FPGA-based trigger logic. Current implementation of the system is functioning in the Borexino detector providing zero dead time spectroscopy data in energy range from 1 up to 100 MeV. Acquisition complex in combination with our custom analysis software is successfully being used for registration of geoneutrinos, as well as search for neutrino signal from GRBs, solar netrino spectroscopy and other aplications.

The system for forming a trigger for the RED-100 liquid xenon detector has been developed. The trigger can be generated for all types of events required to calibrate the detector and data acquisition, including events with one ionization electron. The system has an event detection mechanism where each event is assigned with the timestamp and event type. The trigger system is required in the systems searching for rare events to keep only the necessary information from the ADC array. The characteristics and implementation of the trigger system that provides high efficiency operation even at low-energy events have been described.

Krypton-85 is a technogenic beta-radioactive isotope which produces background in a low-energy region in dark matter and neutrino detectors: in noble gas detectors, especially in liquid Xenon detectors, in organic liquid scintillator detectors. We propose a new method of reduction of the 85Kr isotope in a detector medium based on adding to the detector medium a Krypton sample depleted of the 85Kr isotope and subsequent reduction of the Kr content down to the initial or even lower level with the use of existing methods of purification. This method works because the residual natural Kr is diluted in the depleted one and is removed together with it from Xe since both of them have the same thermodynamic properties. A test cell for measurement of the activity of the depleted Kr has been assembled and the radioactivity of the 25-year-old Krypton has been measured. The measured activity (56 ± 5 Bq/g) recalculated to the air the air activity due to 85Kr decays in the year 1990 (1.20 ± 0.10 Bq/m3) is close to the data on the air activity at that time.

We describe basic principles of electron emission in two-phase xenon and discuss possible ways of spontaneous electron emission. We present a brief summary of experimental results connected to single electron emission including the recent one obtained by the authors. The results of study seem to confirm the hypothesis, that single electron signals originate from the cloud of ionization electrons localised under the liquid-gas interface.

A cryogenic system based on a two-phase closed tubular thermosyphon with 12 mm diameter copper tube is developed. It was used for thermal stabilization of the liquid xenon emission detector RED-100. The nitrogen refrigerant cooled down with a free-boiling liquid nitrogen bath has been used. It was shown that the system supports the RED100 operation at temperature 166 K with accuracy ±1К.

The two-phase cryogenic xenon emission detector RED100 is planned to be equipped by 38 Hamamatsu R11410-20 photomultiplier tubes, which are claimed to be operable at cryogenic temperatures and made of extremely low background materials. A thorough characterization procedure has been carried out for each PMT unit to be installed to the detector. The main results obtained are presented here, including the single photoelectron spectra parameters, a set of gain-representing curves for a wide range of the bias voltage values, typical amplitude integral spectrum of the PMT’s dark count rate and the distribution of 34 PMT samples through their dark count rate for equal gain values. Peculiar characteristics of several PMT units are further discussed and explained.

New results obtained with reactor, accelerator and atmospheric neutrinos will be presented. An emphasis will be put on recent measurements of muon anti-neutrino oscillations in the T2K experiment and first results obtained in the Nova experiment. The status of the search for CP violation in neutrino oscillations will be discussed. Future long baseline neutrino experiments will be also briefly reviewed.

The DarkSide-50 dark matter detector is a two-phase argon TPC installed at Laboratori Nazionali del Gran Sasso at the center of two nested veto detectors, a 30-tonne liquid scintillator neutron veto and a 1,000-tonne water Cherenkov muon veto. While operating in 2014 with a fill of argon extracted from the atmosphere, DarkSide-50 demonstrated its capability to operate in a background-free mode even in presence of the strong radioactive background due to the 39Ar isotope produced by cosmic rays. Today DarkSide-50 is the only noble liquid dark matter detector operating in background-free mode. In 2015 DarkSide was filled with 150 kg of argon extracted from deep underground reservoirs, which was demonstrated to be highly depleted in 39Ar. The combination of these two successes allows to project that DarkSide-20k, a 20-tonne depleted argon detector just proposed for installation at LNGS, will be able to operate completely free of background. The DarkSide-20k detector is set to start operating by 2019 and is projected to be the most sensitive dark matter experiment to start data taking by 2020, with a sensitivity reaching well past the ultimate value possible for xenon-based detectors and close to the ultimate background due to nuclear recoils induced by neutrino cohere scattering. DarkSide-20k will be followed after five years at LNGS by Argo, a 300-tonne dark matter detector also capable of performing a set of very high precision measurement of several solar neutrino sources. Both programs are made possible by significant investments by MIUR and INFN in the procurement of underground argon (Urania Project) and in its additional isotopic rejection of 39Ar (Aria Project).

Two-phase emission detectors using liquid xenon working medium are extremely sensitive to ionization (down to single electrons), can be very massive (in tons scale) and provide active shielding from natural radioactivity in wall-les configuration of the readout system. That is why they found their unique application in the most sensitive experiments searching for cold dark matter in the form of weakly ionizing massive particles (WIMPs) such as LUX, XENON100, and PandaX-II. The last results of those experiments are reviewed in this paper. The current best limits for the interaction cross sections of supersymmetric WIMPs having a mass of 100 GeV/c2 with nucleons were measured with emission detector LUX containing 360 kg of liquid xenon. Emission detectors of the next generation G2, such as LZ with an active detector mass of 7 tons, will either unambiguously detect WIMPs or rule out all current theoretical predictions for WIMP existence. Detectors of the G3 generation of up to 20 ton mass will be used for multiple purposes including detection of double beta neutrinoless decay and low-energy neutrinos.

In this talk I will review and disucss the results obtained with the KASCADE-Grande in the study of the spectrum, chemical composition and anistropy of primary cosmic rays in the 10^16-10^18 eV energy range

Large volume detectors designed for the detection of astrophysical neutrinos such as IceCube register cosmic ray-induced atmospheric muon bundles at a rate of several thousand events per second. Due to the large amount of surrounding material, the effective energy threshold for muons reaching the detector lies at approximately one TeV. By careful evaluation of event profiles it is possible to address cosmic ray and particle physics issues in an unprecedented energy range. First results from the analysis of one year of IceCube data will be presented and their implications discussed.

After a brief description of the main scientific findings at Chacaltaya, we presented the possibility of a network to search for Extensive Air Showers originated from primary cosmic rays at energies greater than 10^^15 eV. Such EAS could be measured in the existing high altitude laboratories deployed in the region of Latin America. The Chacaltaya EAS array, located at 5230 m a.s.l. could be take as the centre of the network from where the distances of the others could be at El Alto (4000 m a.s.l.) and Cota Cota (3600 m a.s.l.) in Bolivia, at the distances of 15 and 25 Km from Chacaltaya respectively while the laboratory of Putre (3600 m a.s.l.) in Chile and Huancayo (3500 m a.s.l.) in Peru, are at the distances about 250 and 700 km respectively from Chacaltaya. Searching for simultaneous and parallel EAS events at multiple observatories is very important to look for non random cosmic rays. One of main aim of this network could be to search for simultaneous and parallel EAS events at multiple EAS observatories for example due to Gerasimova-Zatsepin effect at high altitude laboratories. Besides this, study other astrophysical phenomena, like high energy gamma rays from GRBs could be possible with the same array.

The TAIGA project is aimed at solving the fundamental problems of gamma-ray astronomy and physics of ultrahigh energy cosmic rays with the help of the complex of detectors, located in the Tunka valley (Siberia, Russia). TAIGA includes a wide-angle large area Tunka-HiSCORE array, designed to detect gamma-rays of ultrahigh energies in the range 20 - 1000 TeV and charged cosmic rays with energies of 100 TeV - 100 PeV, large area muon detector to improve the rejection of background EAS protons and nuclei and a network of imaging atmospheric Cherenkov telescopes for gamma radiation detection. We discuss the goals and objectives of the complex features of each detector and the results obtained in the first stage of the HiSCORE installation.

Экспериментальный комплекс НЕВОД включает в себя черенковский водный детектор, систему калибровочных телескопов и координатные детекторы. В докладе рассматриваются основные этапы создания экспериментального комплекса, направления исследований, полученные результаты, в том числе касающиеся решения мюонной загадки, а также перспективы его дальнейшего развития.

Ключом к решению "мюонной загадки" – проблемы избытка мюонов в ШАЛ по сравнению с ожидаемым - может быть исследование поведения энергетических характеристик мюонной компоненты с изменением энергии первичных частиц. Представлены результаты измерений зависимостей энерговыделений наклонных групп мюонов в черенковском водном детекторе НЕВОД от зенитного угла и от локальной плотности мюонов. В качестве меры энерговыделения используется суммарное число фотоэлектронов, зарегистрированных всеми ФЭУ калориметра НЕВОД. Локальная плотность мюонов, которая дает оценку энергии первичных частиц, измеряется по данным координатно-трекового детектора ДЕКОР. Полученные экспериментальные данные сопоставлены с результатами расчетов, основанными на моделировании мюонной компоненты ШАЛ с помощью программы CORSIKA.

Проведен анализ пространственного распределения черенковского света, генерируемого каскадными ливнями в ЧВД НЕВОД. Отбирались ливни, рожденные окологоризонтальными мюонами, треки которых определены с высокой точностью с помощью координатного детектора ДЕКОР. Впервые экспериментально получены зависимости интенсивности черенковского света от глубины развития ливня на разных расстояниях от его оси.

Анализируются изменения интенсивности групп мюонов, образующихся в результате взаимодействия первичных частиц космических лучей с энергией порядка ПэВ и регистрируемых на поверхности Земли. Рассмотрены сезонные вариации интенсивности, барометрический и температурный эффекты, корреляции с высотой различных уровней остаточного атмосферного давления. Показано, что вариации интенсивности объясняются изменениями функции пространственного распределения мюонов на уровне наблюдения, связанными с геометрическим изменением эффективной высоты формирования групп.

В работе представлены результаты исследований вариаций потока мюонов космических лучей во время мощного форбуш-эффекта, зарегистрированного мюонным годоскопом УРАГАН 22 июня 2015 года. По угловому распределению потока мюонов получена зависимость амплитуды падения его интенсивности от энергии первичных частиц в области выше 10 ГэВ. Исследованы изменения этой зависимости на разных фазах развития форбуш-эффекта. На основе анализа пространственно-угловых вариаций потока мюонов получены значения параметров вектора локальной анизотропии и уникальные мюонные снимки. Проанализированы характеристики гелиосферных и магнитосферных возмущений во время анализируемого события.

Gamma-ray bursts duration distributions properties for events registered by experiments SMM/GRS, CGRO/BATSE, HETE2, WIND/KONUS, KONUS-WIND/VENERA 13 or 14, GRANAT/PHEBUS, GRANAT/SIGMA, Swift/BAT, RHESSI, ULYSSES, GRANAT/WATCH, Fermi/GBM are considered. GRBs observed since 1967 and now several thousends of events were listed in more than 15 catalogues. Gamma-ray bursts duration distribution was the first analysed using data of BATSE instrument onboard the CGRO. Bursts duration was described by the time intervals in which the integrated counts from the burst increases from 25% to 75% (t50 ) and from 5% to 95% (t90). The GRBs duration distribution analysis had shown the existence of two bursts classes: long (t90 more than 2 s) and short (t90 less than 2 s). But results of similar distributions for bursrs observed by other detectors have shown shifting of boundary between short and long events from value of 2 s. For example, Swift/BAT GRBs subset analysis give the value of ~1 s for this separator point. Moreover, t90 has dependence from instrument registered this burst – it is function of detector sensitivity threshold and operation energy band. For instance, the duration of GRB060418 burst t90 is ~52 s according to Swift/BAT data and only 36 s according to RHESSI data. Therefore, the type of GGB (whether it short or long) should be defined only taking into account distinctive features of instrument detected this event. Firstly third intermediate GRBs subgroup was found some years ago in BATSE GRB duration and duration-hardness distributions. Attributes of this subgroup appearance in events subsets for various detectors are discussed.

The DarkSide-50 is the dual phase Liquid Argon Time Projection Chamber (LAr TPC) based experiment, builded for the direct dark matter search which currently is taking data in the underground facility at Laboratori Nazionali del Gran Sasso (LNGS). The detector was assembled, tested and filled first with atmospheric Argon (in 2013) and took a successful two years run accumulating the exposure of ~1420 kg d. In April of 2015 the detector was filled with low radioactivity Argon (depleted in Ar39) from the underground source in Colorado (Kinder Morgan co.) and it is in the WIMP search mode since then. The LAr TPC with an active mass of ~46 kg is surrounded by the 30 tonne organic scintillator containing vessel equipped with 110 PMTs used as the neutron veto, which, in its turn, is placed inside the 1kton water Cerenkov detector equipped with 80 PMTs and used as the cosmic rays muons veto. The detailed description of all three detectors will be given together with the first WIMP search results from both: the AAr run with exposure of ~1420 kg d as well as the UAr run with a ~2000 kg d of exposure.

The DarkSide Collaboration has started consideration of DarkSide-20k, a direct WIMP search with a Liquid Argon Time Projection Chamber (LAr-TPC) with an active (fiducial) mass of 23 (20) tonnes. The DarkSide-20k LAr-TPC will be deployed in the shield/veto facility already built in support of the DarkSide-50 experiment in the Gran Sasso underground laboratory (LNGS). DarkSide-20k will be a detector with ultra-low background levels, the ability to measure its backgrounds in situ, and sensitivity to WIMP-nucleon interactions with cross sections of 9×10E-48 cm2 (9x10E-47 cm2) for WIMPs of 1 TeV/c2 (10 TeV/c2) mass, achieved in a background-free exposure of 100 t yr accumulated in a run of 5 yr. We believe, in particular, that the ability to identify, measure, and reject background will ultimately define the sensitivity of direct dark matter searches. The sensitivity of DarkSide-20k compares favourably with the sensitivity of other projects to start data taking before 2020. DarkSide-20k could become the most powerful dark matter experiment searching for high mass dark matter to start data taking by 2020. The use of the two-phase argon technology afford a sharp definition of the fiducial volume e effecting a strong reduction of the systematic error that dominates the measurement of 7Be neutrinos in Borexino. To meet this challenge, DarkSide-20k will exploit the auxiliary facilities including radon-free clean rooms, already built at LNGS as part of the DarkSide program. It will also use the water muon veto constructed for the DarkSide program. DarkSide-20k will be instrumented with SiPMs as photosensors and will establish the entire chain of production, purification, transport, and storage of low-radioactivity argon at the multi-tonne level. In short, DarkSide-20k will perform the most sensitive search for dark matter yet proposed and will also provide a convincing foundation for a 100 t scale detector. A summary of the future experiment and the improvement of the existing facilities will be presented.

DarkSide 20k is a dark matter search experiment whose active target is argon in a double phase TPC. The residual internal background consists in the 39Ar isotope inside the target. The collaboration developed a strategy consisting in the extraction of Argon from underground CO2 wells, than distilled in a very tall cryogenic distillation column. DarkSide 50 already demonstrated the depletion in 39Ar in the underground Argon by a factor bigger than 300. Aria project covers the second part of the strategy and consists in a 350 m tall column installed in Italy, in the Sardinia region, that exploits the tiny difference in volatility due to the difference in isotopic mass. Codes for calculation of relative volatility of argon isotopes, based on the extensive and detailed models available in the literature have been developed and short cut simulations based either on the McCabe-Thiele method or the Fenske-Underwood-Gilliland (FUG) method, or its derivative Wynn-Underwood-Gilliland (WUG) showed that every single pass in the column should reduce the 39Ar content by a factor 10. The same technology can be applied to the separation of other stable isotopes of commercial interest. A description of the Aria project will be presented.

Pyroelectric crystals, such as LiNbO3 or LiTaO3 being under influence of temperature gradient produce electric field up to 106 kV/cm. It was experimentally confirmed that the crystal installed in the chamber with residual gas pressure about 1 mTorr could be used for generation of X-Ray radiation [1,2] with energy up to about 100 keV, as well as electrons [3] and neutrons with energy 2.45 MeV [4]. Due to the unique properties such as On/Off mode of operation and absence of radioactive materials such generators seems to be promising tool for calibration of neutrino and dark matter detectors. The experimental setup for the research and development of pyroelectric generators is presented. References [1]. Brownridge, J D.,“Pyroelectric x-ray generator,” Nature, 358, pp. 277-278 (1992). [2].

We discuss the possibility to produce a modulated monochromatic neutrino beam. Monochromatic neutrinos can be obtained in electron capture by nuclei of atoms or ions. Hydrogen-like ions are of particular interest. It is shown that monochromatic neutrino beam from such hydrogen-like ions with nuclei of non-zero spin can be modulated because of different probabilities of electron capture from hyperfine states. Modulation arises by means of inducing of electromagnetic transitions between the hyperfine states. Requirements for the hydrogen-like ions with necessary properties are discussed. A list of the appropriate nuclei for such ions is presented.

In number of active regions the fluctuations of radio emission of different types of sources (spots, compact and extended intersunspot sources (ISS)) were compared with the fluctuations in magnetic fields of sunspots. More significant correlation between the variations in magnetic field and radio emission was observed for sunspots and compact ISS. We adopt the cross-correlation analysis, wavelet analysis, and statistical tests to deduce the results. The model of the shallow sunspot’s eigen oscillations is discussed for explanation of the origin of quasi-periodic oscillations in sunspots and ISS.

The processes of neutrino production of electron positron pairs, $\nu \bar\nu \to e^- e^+$ and $\nu \to \nu e^- e^+$, in a magnetic field of arbitrary strength, where electrons and positrons can be created in the states corresponding to excited Landau levels, are analysed. The mean values of the neutrino energy losses due to these processes are calculated. The results can be applied for calculating the efficiency of the electron-positron plasma production by neutrinos in the conditions of the Kerr black hole accretion disc considered by experts as the most possible source of a short cosmological gamma burst. The presented research can be also useful for further development of the calculation technic for an analysis of quantum processes in external active medium, and in part in the conditions of moderately strong magnetic field, when taking account of the ground Landau level appears to be insufficient.

В отличие от большинства наземных детекторов космических лучей, мюонный годоскоп УРАГАН (НИЯУ МИФИ) позволяет исследовать не только интегральный темп счета зарегистрированных частиц, но и пространственно-угловые характеристики потока мюонов на уровне Земли. В докладе приводится анализ наиболее мощных корональных выбросов масс (КВМ), произошедших в 2015 году, фронт которых был направлен в противоположную от Земли сторону. Подобные негеоэффективные КВМ оказывают более существенное влияние на угловое распределение мюонов, чем на вариации в интегральном темпе счета мюонного годоскопа. Такие наблюдения позволяют исследовать подобные события не только в космосе, но и на поверхности Земли.

Поток первичных заряженных космических лучей (ПКЛ) модулируется магнитным полем гелиосферы, на состояние которого влияют различные гелиосферные процессы. После взаимодействия ПКЛ с ядрами атомов атмосферы Земли эти модуляции передаются потоку вторичных мюонов. Мюонный годоскоп УРАГАН позволяет отслеживать изменение не только интенсивности потока мюонов, но и его углового распределения в широком диапазоне зенитных углов (0-80º). В работе приводятся некоторые результаты поиска предикторов геоэффективных гелиосферных процессов на основе данных МГ УРАГАН.

Проект новой установки для регистрации атмосферных нейтронов (УРАН) основан на новом подходе к исследованию широких атмосферных ливней (ШАЛ). Установка включает 72 эн-детектора, способных регистрировать сразу две основные компоненты ШАЛ: адронную через тепловые нейтроны и электромагнитную по групповому прохождению заряженных частиц. В качестве регистратора нейтронов и заряженных частиц используется специализированная сцинтилляционная композиция, представляющая собой гранулированный сплав кристаллов на основе порошка ZnS(Ag) с примесью B2О3.

В настоящее время на базе Уникальной научной установки «Экспериментальный комплекс НЕВОД» создается детектор кластерного типа НЕВОД-ШАЛ, предназначенный для регистрации широких атмосферных ливней в диапазоне энергий 10^15-10^17 эВ, который соответствует области излома энергетического спектра первичных космических лучей. В состав детектора НЕВОД-ШАЛ общей площадью ~ 2×10^4 кв.м. будет входить 12 кластеров сцинтилляционных счетчиков частиц электронно-фотонной компоненты ШАЛ. Каждый кластер состоит из 16 счетчиков, объединенных в 4 детектирующие станции (ДС). Амплитудная информация с ДС кластера поступает в локальный пункт сбора и первичной обработки данных, осуществляющий оцифровку аналоговых сигналов, отбор событий по заданным внутрикластерным триггерным условиям, передачу экспериментальных данных в систему сбора и обработки детектора НЕВОД-ШАЛ, а также проведение мониторинга рабочих параметров всех элементов кластера. В докладе обсуждаются характеристики основных элементов сцинтилляционных счетчиков и ДС, а также устройство, технические характеристики и функциональные особенности регистрирующей системы кластера детектора НЕВОД-ШАЛ.

В НИЯУ МИФИ создан новый сцинтилляционный мюонный годоскоп для изучения вариаций потока мюонов космических лучей. При сравнимых основных характеристиках (эффективной площади, точности реконструкции треков мюонов, величине «живого» времени и пр.) с уже существующими в НИЯУ МИФИ годоскопами (ТЕМП и УРАГАН), отличительной особенностью данного детектора являются модульная конструкция, обеспечивающая относительно простую транспортабельность, и низкая потребность в обслуживании, дающая возможность длительной автономной работы. Представлены и обсуждаются первые результаты изучения вариаций мюонов космических лучей, полученные на новом сцинтилляционном мюонном годоскопе.

В НИЯУ МИФИ разрабатывается крупномасштабный координатно-трековый детектор на дрейфовых камерах для регистрации окологоризонтального потока мюонов космических лучей сверхвысоких энергий совместно с экспериментальным комплексом НЕВОД. На данный момент создан прототип детектора (КТУДК), состоящий из 16 дрейфовых камер, формирующих две координатные плоскости, установленные с противоположных сторон от бассейна черенковского водного детектора. В докладе приводится описание регистрирующей системы данной установки, которая в дальнейшем будет расширена и будет использоваться в полноразмерном детекторе.

Review presented of recent publications about experimental data, theoretical models and interpretations. The sources of electrons in the heliosphere are numerous and mainly related to the Sun, Interpalanetary and interstellar medium, planets and other astrophysical objects. The energy spectra of electrons from thermal to highest energies are composed from different components due to transport processes in the phase space from mentioned sources. They are of fundamental physical interest per se and of technical applications as well. We summarize the gained knowledge in the visual simple shape as tables, plots and formulae for the aim to turn attention on unsolved questions and possible perspectives of obtaining new information.

Dynamics of the latitudinal profiles penetrating into magnetosphere solar protons is studied using particle spectrometer data on board of the low latitude polar satellite CORONAS-F. Formations of several different types of the profiles during magnetic storms are considered.

The gamma-ray background physical origin for low altitude orbits defined by:ndiffuse cosmic gamma-emission, atmospheric gamma-rays, gamma-emission formed in interactions of charged particles (both prompt or activation) and transient events such as electrons precipitations and solar flares. The background conditions in the energy range from 0.1 MeV up to several MeV for low and high inclination low altutude orbits differ due frequency of Radiation Belts (included South Atlantic Anomaly) passes and cosmic rays rigidity. The detectors and satellite constructive elements activated by trapped in Radiation Belts or moving along magnetic lines charged particles. The AVS-F apparatus was intended for the solar flares hard X-ray and gamma-ray emission characteristic studies and for gamma-ray bursts detection. It was installed onboard the specialized automatic station CORONAS-F and operated since july, 2001 up to December, 2005. The onboard calibration was made every mounth due to 11 background lines. The orbit inclination of CORONAS-F satellite was ~82.5 grad and it passed through the Earth radiation belts 4 times per 90 min. In this case the gamma--events observations are possible only in equatorial orbit parts or polar caps regions and this orbits part passing duration is not enough for activation lines de-excitation. For this reason it is possible to use the background count rate temporal profile approximation by 4-5 order polynomials in equatorial regions, and 1-3 order polynomials or constant in polar caps. The polynomials’ coefficients supposed similar for identical spectral channels for each analyzed equatorial part taken into account normalization coefficients defined due to Kp-indexes study within period corresponding calibration coefficients being approximately constants.

The overview of the main problems and methods of cosmoparticle physics, studying fundamental relationship of micro- and macro-worlds will be accompanied by the demonstration of the facility of Virtual Institute of Astroparticle physics (VIA) activity as a well proven basis for scientific collaborative work and education at distance.

The present status of direct detection of Dark Matter (DM) particles will be summarized, with particular care to the DAMA model-independent DM annual modulation results. Arguments on comparisons will be addressed showing that there is large room for compatibility between positive signals and negative hints, considering both the different adopted procedures and techniques, the different experimental observables, the different exposures, the existing experimental and theoretical uncertainties and the widely open scenarios for astrophysical, particle and nuclear Physics aspects. Recent results on diurnal investigation will also be introduced. Realistic experimental perspectives will be, finally, addressed with attention to some particular cases.

Neutrino telescope IceCube has recently discovered astrophysical neutrinos with energies in the 10 TeV – 3 PeV range. It challenged existed theoretical models due to unexpected soft spectrum 1/E^{2.5} of neutrinos. Together with limits from diffuse gamma-ray flux measured with Fermi experiment this excluded most of existed predictions. In my talk I'll review theoretical models, which can explain observed data both with Galactic and extra-galactic sources of neutrinos.

The ESA Planck satellite, launched in 2009, produced full-sky maps of the microwave sky in both temperature and polarization over a broad range of frequencies. An analysis of these maps allows us to characterize the initial conditions of our universe. The Planck Collaboration has released two sets of papers with results on cosmology: one in 2013 and another in 2015. I will discuss the implications of these results for our understanding of the physics at play in the very early universe. I will also discuss prospects for improving our understanding with future CMB probes, in particular of the CMB B mode polarization.

The GAMMA-400 gamma-ray telescope with excellent angular and energy resolutions is designed to search for signatures of dark matter in the fluxes of gamma-ray emission and electrons + positrons. Precision investigations of gamma-ray emission from Galactic Center, Crab, Vela, Cygnus, Geminga, and other regions will be performed, as well as diffuse gamma-ray emission, along with measurements of high-energy electron + positron and nuclei fluxes. Furthermore, it will study gamma-ray bursts and gamma-ray emission from the Sun during periods of solar activity. The GAMMA-400 energy range is expected to be from ~20 MeV up to TeV energies for gamma rays, up to 10 TeV for electrons + positrons, and up to 10E15 eV for cosmic-ray nuclei. For 100-GeV gamma rays, the GAMMA-400 angular resolution is ~0.01° and energy resolution is ~1%; the proton rejection factor is ~5x10E5. GAMMA-400 will be installed onboard the Russian space observatory.

The description of the onboard experiment MONICA for study of the fluxes of cosmic ray energetic ions from H to Ni in the energy range 10-300 MeV/n in near-Earth space is presented. The MONICA main scientific goal is the measurement of the ion charge states, as well as elemental, isotope composition and energy spectra of Solar Energetic Particle (SEP) fluxes for individual SEP events, and study the evolution of these characteristics in time. The experiment MONICA will be able to investigate the ion and isotopic composition of Anomalous Cosmic Rays (ACR), Galactic Cosmic Rays (GCR), and the isotope fluxes in the Earth’s inner zone. The observation of the ion fluxes will be carried out with high acceptance multilayer silicon telescope-spectrometer onboard the polar-orbiting satellite. The satellite orbit parameters (circular, altitude is about 600 km, polar) were chosen for the realization of the ion charge state measurement method based on using of the Earth magnetic field as a separator of the ion charge. This technique is unique possible for ion energies more than 10 MeV/n.

Measurements of electron and positron spatial distributions in energy range from 80 MeV to several GeV below the geomagnetic cutoff rigidity were carried out using the PAMELA magnetic spectrometer. The instrument is installed on board the Resurs-DK satellite which was launched June 15th 2006 on an elliptical orbit with the inclination 70 degrees and the altitude 350-600 km. The procedure of trajectories calculations in the geomagnetic filed gives a way to separate stably trapped and short lived albedo components produced in interactions of cosmic ray protons with the residual atmosphere. The work presents spatial distributions of trapped, quasitrapped and short-lived albedo electrons and positrons in the near Earth space. Electron to positron ratio points out on different production mechanism of trapped and quasitrapped particles On behalf of PAMELA collaboration

The orbital spectrometer PAMELA is the first instrument allowing direct measurement of solar relativistic particles. Before such information was obtained from the ground-based installations – neutron monitors which detected the secondary particle component generated by the solar energetic particles (SEP) in the Earth’s atmosphere. Moreover, the data in the SEP energy range of several hundred MeV was also scarce and mainly covered by balloon observations which spend at high altitudes only limited time intervals. Since its launch in 2006 PAMELA recorded 25 SEP events with protons above 80 MeV/nucleon. In several events the Helium nuclei were also detected. The solar proton spectra taken from PAMELA are in satisfactory agreement with the results in the adjacent energy ranges, such as of GOES and ARINA in the lower energies and of neutron monitors in the higher energy. The combined SEP energy spectra from ~10 MeV to several hundred MeV or even several GeV demonstrate various and complicated forms which argue for numerous processes affecting SEPs in the course of acceleration and propagation on the Sun and interplanetary space.

On the 15th of June 2006, the PAMELA satellite-borne experiment was launched from the Baikonur cosmodrome and it has been collecting data since July 2006. The apparatus comprises a time-of-flight system, a silicon-microstrip magnetic spectrometer, a silicon-tungsten electromagnetic calorimeter, an anti-coincidence system, a shower tail counter scintillator and a neutron detector. The scientific objectives addressed by the mission are the measurement of the antiprotons and positrons spectra in cosmic rays, the hunt for antinuclei as well as the determination of light nuclei fluxes from hydrogen to oxygen in a wide energy range and with very high statistics. In this paper the identification capability for H, He, Li and Be isotopes using using two different detector systems will be presented, combining the rigidity measurement from the magnetic spectrometer with the velocity information derived either with the time-of-flight or with multiple dE/dx measurements in the calorimeter. Preliminary results of the fluxes and the isotopic ratios will also be presented.

The nine years of data taking in space of the experiment PAMELA are providing interesting information concerning the origin and propagation of both galactic and solar cosmic rays. The measured antiparticle component of the cosmic radiation shows features that can be interpreted in terms of dark matter annihilation or pulsar contribution. The precise measurements of the energy spectra of protons, helium and light nuclei and their isotopes, electrons, as well as of their arrival distribution challenges our basic vision of the mechanisms of production, acceleration and propagation of cosmic rays in the galaxy. The study of the time dependence of the various components of the cosmic radiations clearly shows solar modulation effects as well as charge sign dependence of these effects. PAMELA measurement of the energy spectra during solar energetic particle events fills the existing energy gap between the highest energy particles measured in space and the ground-based domain. Furthemore, providing pitch angle measurements, it allows the study of the effects of particle transport within interplanetary space over a broad range in energy. Furthermore, by sampling the particle radiation in different regions of the magnetosphere, PAMELA data provide a detailed study of the Earth’s magnetosphere. This talk illustrates the most recent scientific results obtained by the PAMELA experiment.

The satellite-borne PAMELA experiment has been continuously collecting data since it was launched on 15th June 2006, from the Baikonur cosmodrome. The instrument, particularly suited for particle and antiparticle identification, has detected the charged component of cosmic rays over a wide energy range and with unprecedented statistics. The instrumental characteristics and the quasi-polar orbit, with an inclination of 70 degrees, allowed to measure charged particles down to few tens of MeV. In particular, the time variation of galactic proton, electron and positron spectra has been measured at Earth extending down to about 80 MeV, 70 MeV and 200 MeV respectively and up to about 50 GeV. The time and energy dependence of these fluxes has been studied during the A<0 solar minimum of solar cycle 23, from 2006 to 2009, providing important information on the propagation mechanisms of charged cosmic rays in the heliosphere and allowing to investigate charge dependent solar modulation effects.

The PAMELA space experiment is providing first direct observations of Solar Energetic Particles (SEPs) with energies from about 80 MeV to several GeV in near-Earth orbit, bridging the low energy measurements by other spacecrafts and the Ground Level Enhancement (GLE) data by the worldwide network of neutron monitors. Its unique observational capabilities include the possibility of measuring the flux angular distribution and thus investigating possible anisotropies associated to SEP events. The analysis is supported by an accurate back-tracing simulation based on a realistic description of the Earth's magnetosphere, which is exploited to estimate the SEP energy spectra as a function of the asymptotic direction of arrival with respect to the Interplanetary Magnetic Field (IMF). In this work we report the results for the May 17, 2012 event.

In the framework of the PAMELA experiment the features of the large-scale anisotropy has been measured within the energy range 1-20 TeV/n. The measurements was carried out with the use of the calorimeter on the base of the hypothesis about the existence of the dipole anisotropy. The amplitude and phase of the dipole were obtained. The results are in agreement with the ground-based observations. On behalf of PAMELA collaboration

In this work new measurements of reentrant albedo deuteron fluxes in the PAMELA experiment are presented. PAMELA is an international experiment aimed on measurement of cosmic ray particles in wide energy range. In particular, PAMELA detectors are able to identify deuterons. In this work the results of trajectory reconstruction analysis for reentrant deuterons are presented for particles with energies from 100 to 400 MeV/nucleon. On behalf of PAMELA collaboration

Experimental measurements of the antiproton flux in the near Earth space are important for astrophysics, including the exploration of the hypothetical "dark" matter particle properties. From June 2006 up to the present time, the scientific experiment PAMELA on board the spacecraft Resurs-DK1 was carrying out the study the various cosmic rays components in the wide energy range. PAMELA spectrometer allows registering low-energy antiprotons (E <1 GeV) by two different detectors independently: the magnetic spectrometer and the coordinate-sensitive electromagnetic calorimeter. This paper presents a method of antiproton’s identification, stopping in the calorimeter. It based on the analysis of the topology of antiproton and a secondary charged meson tracks which arising in the annihilation process. The application of this method will independently confirm the results of the magnetic analysis, and increase of statistics due to a greater geometric factor of calorimeter in comparison with the magnetic spectrometer is expected. On behalf of PAMELA collaboration

Penetration of Schumann resonances energy from the Earth-ionosphere resonance cavity into the circumterrestrial space is examined. This study focuses on estimates of Alfvén wave amplitude and spectra in the frequency range of 7-50 Hz which can be observed by low-orbiting satellites. Differences in Schumann resonances observation conditions between the nighttime and sunlit sides of the ionosphere are analyzed. Particular emphasis has been placed on the ionospheric Alfvén resonator (IAR) excited by both the global thunderstorm activity and individual lightning discharges. IAR spectra in the frequency range of 0.5-10 Hz are calculated for ionospheric altitudes. The calculated spectral amplitudes of IAR and Schumann resonances are compatible with C/NOFS satellite observations. To explain a shift of IAR resonant frequencies observed during C/NOFS satellite passage through terminator region, the IAR model is developed in which an interference of Alfvén waves reflected from the ionospheric E-layer and the IAR upper boundary is taken into account.

The sampling imaging electromagnetic calorimeter of ~ 16.3 radiation lengths and ~ 0.6 nuclear interaction length designed and constructed by the PAMELA collaboration as a part of the large magnetic spectrometer PAMELA. Calorimeter consists of 44 single-sided silicon sensor planes interleaved with 22 plates of tungsten absorber (thickness of each tungsten layer 0.26 cm). Silicon planes are composed of a 3x3 matrix of silicon detectors, each segmented into 32 read-out strips with a pitch of 2.4 mm. The orientation of the strips of two consecutive layers is orthogonal and therefore provides two-dimensional spatial information. Due to the high granularity, the development of hadronic showers can be study with a good precision. In this work a Monte Carlo simulations based on Geant4, performed using different available models, and including detector and physics effects, compared with the experimental data obtained on the near Earth orbit. The response of the PAMELA calorimeter to hadronic showers investigated including shower radius, longitudinal and transverse shower profiles etc.

Recent experiments in high enegry cosmic ray physics, PAMELA and AMS-02, excite new interest to the mechanisms of generation of galactic antiparticles. In spite of the fact that global picture coincides with the predictions of the standard theory, there are some black spots stimulating scientists to involve into research a particularly new physics like dark matter. In the present work, we make an attempt to estimate the impact of standard neutrino processes into the total flux of secondary antiprotons detected by contemporary experiments.

It is known that the vortex gravitational field in rotating cylindrically symmetric configurations leads to an exotic contribution in the total effective stress-energy tensor, which is favorable for the formation of cylindrical wormhole throats. This leads to an opportunity to obtain wormholes without exotic matter, and there are examples of such exact wormhole solutions (including vacuum ones and those with a massless scalar field). However, none of them are asymptotically flat, hence they cannot describe local configurations in our Universe, which is, on the average, very weakly curved. A possible way out is to build configurations with flat asymptotic regions by the cut-and-paste procedure: on both sides of the throat, a wormhole solution is matched to a properly chosen region of flat space (taken in a rotating reference frame) at some surfaces $\Sigma_-$ and $\Sigma_+$. It is shown, however, that if we the throat region has, as a source of gravity, a minimally coupled scalar field with an arbitrary self-interaction potential, then one or both thin shells appearing on $\Sigma_-$ and $\Sigma_+$ inevitably violate the Null Energy Condition. In other words, although rotating wormhole solutions are easily found without exotic matter, such matter is still necessary for obtaining asymptotic flatness.

S.V. Bolokhov, K.A. Bronnikov, P.A. Korolyov, M.V. Skvortsova We construct explicit examples of globally regular static, spherically symmetric solutions in general relativity with scalar and electromagnetic fields, describing (1) traversable wormholes with flat and AdS asymptotics and (2) regular black holes, in particular, black universes. (A black universe is a regular black hole with an expanding, asymptotically isotropic space-time beyond the horizon.) The existence of such objects requires invoking scalars with negative kinetic energy (``phantoms'', or ``ghosts''), which are not observed under usual physical conditions. To account for that, the so-called ``trapped ghosts'' were previously introduced, i.e., scalars whose kinetic energy is only negative in a restricted strong-field region of space-time and positive outside it. This approach leads to certain problems, including instability (as we illustrate by derivation of an effective potential for spherical pertubations of such systems). To avoid that, we use for model construction what we call ``invisible ghosts'', i.e., phantom scalar fields sufficiently rapidly decaying in the weak-field region. The resulting configurations contain different numbers of Killing horizons, from zero to four. Their global structure has been studied with the aid of Carter-Penrose diagrams.

We demonstrate that non-zero mass difference between electron and positron that breaks CPT-symmetry produces also an electric charge non-conservation and non-zero photon mass.Cosmological bounds on non-zero photon mass can be transformed into bounds on electron-positron mass difference that 10-15 order of magnitude stronger than existing direct bounds

The $U_L(2)\bigotimes U_R(2) $ gauge model for the unified theory of the electromagnetic and weak interactions which is free from the auxiliary self-interaction scalar field is developed. Due to breaking the initial symmetry, the $SU_L(2)\bigotimes U_R(1) $ Lagrangian is derived. The obtained $SU_L(2)\bigotimes U_R(1) $ Lagrangian contains all the terms corresponding to the free boson and fermion fields as well as to interactions between them, as they take place in the Standard Model consideration. All boson fields, including the Higgs one, directly arise due to breaking the initial symmetry, and are generated by the initial gauge fields. The Higgs fields are studied in detail. We show that there is a wide spectrum of states of the Higgs bosons. The Higgs particle masses in such derivd states are calculated.

Fermions are considered in a multidimensional space with two extra dimensions. Fermion Lagrangian contains coupling to a metric of deformed extra space. We show that the point-like defect on a space with topology of sphere leads to fermion interaction with such defect and calculate cross section of a fermion scattering on such defect.

The application of the coordinate compensation method was examined for the detectors of the time-of-flight system in the high energy gamma ray telescope. The passage of gamma rays with an energy of 1000 GeV through a converter-tracker and through the time-of-flight system was simulated for the typical telescope. Three options of the time-of-flight system were considered with using the coordinate compensation method in the start-detector and in the stop-detector( both detectors used this method, both detectors didn't use it, the start-detector used this method and the stop-detector didn't use it). For all options were calculated the time-of-flight spectra for the secondary charged particles arising in the converter-tracker of the high energy gamma ray telescope and passing through the time-of-flight system. It was shown that the coordinate compensation method is impractical in the stop-detector.

The South Atlantic Anomaly (SAA) dynamics in high-energy proton fluxes was investigated from 2006 to 2014 on the bases ARINA experiment data. This experiment on board the Resurs-DK1 satellite is carried out since 2006 and till now. The instrument detects protons in an energy range from 30 MeV to 100 MeV. The drift of positions (longitudes) of the proton flux maximum and the Earth's IGRF model magnetic field minimum in the SAA region at different L-shells (L = 1.2 – 1.5) were considered in this work. These drifts were compared. It was shown that the average velocities of the SAA’s longitude drift are practically the same and this value about 0.4 ± 0.1 degrees in a year in the western direction.

Gamma-telescope GAMMA-400 is designed to measure fluxes of γ-rays and the electron–positron cosmic ray component possibly associated with dark matter particles annihilation or decay; and to search for and study in detail discrete γ-ray sources, to investigate the energy spectra of Galactic and extragalactic diffuse γ-rays, and to study γ-ray bursts (GRB) and γ-rays from the active Sun. GAMMA‑400 gamma-ray space-based telescope scientific goals require fine angular resolution. GAMMA-400 is the pair production telescope. In the converter-tracker the incident gamma-quantum convert into electron-positron pair in the tungsten layer and then the tracks are registered by silicon-strip position-sensitive detectors. Multiple scattering processes become a significant obstacle in the incident gamma direction reconstruction for energies below several GeV. The method of utilising this process to improve the resolution is proposed in the presented work.

The development of tritium identification methods in the PAMELA experiment are discussed in this work. Particle magnetic rigidity, velocity and energy losses in time-of-flight and magnetic spectrometer detectors were used for the tritium identification. Here we discuss the method of separation of tritium on the background of other particles. Criteria for selection of tritium nuclei in the range of the magnetic rigidities from 0.5 to 3.0 GV were built and the tritium instrument spectrum for the same rigidity range was constructed. Key words: cosmic radiation, tritium, selection criteria.

Studying high-energy (> 50 GeV) cosmic gamma radiation raises a problem of selection of neutral gamma-rays from a background of charged particles. The problem is embarrassed by the *backsplash* effect. The backsplash consists, in the main, of low‑energy (1 MeV) secondary photons moving backwards and is produced by any high-energy gamma quantum. A charged-particle rejection method using the anticoïncidence and time-of‑flight systems is proposed. Charged-particle events are distinguished from those being triggered by high-energy gamma-rays producing backsplash. The method is based on the time separation of signals. It allows us to keep the gamma-ray detection efficiency high up to high energies.

Evolution of dark matter, consisting of WIMP- and SIMP-components, possessing Coulomb-like interaction, which implites in its term existance of termal background of this interaction carriers, is considered. Temperature of SIMP-component is estimated as a function of time.

The additional detector is located between calorimeters of high energy gamma-ray telescope to monitor the backsplash effect.The simulation results of total absorbed energy in this detector are presented. The temporal and spatial characteristics of the total absorbed energy are presented for protons and gamma rays with energies of 500 and 1000 GeV. These results are useful to minimize the backsplash effect on the efficiency of gamma-ray registration.

Today a problem of acceleration and transport of charged particles in solar active processes (flares, shocks) is important as usual. Some current and future space experiments (ACE, MONICA) are aimed for the measurement of a number of physical characteristics of solar energetic particles (SEP) such as intensity, composition, energy spectra et al. Among them there is a poorly investigated charge state distribution of high-energy ions. Ions of iron in SEP is especially valuable for study because they contain information about temperature in the acceleration region on the Sun and thickness of solar substance passing by SEP. Method based on using of Earth’s magnetic field and onboard satellite instrument (telescope-spectrometer) for nuclear identification is applied for solving this experimental task. Spectrometer-telescope consisting of plastic scintillation and silicon layers is proposed for nuclear identification and considered in detail in this report. Main physical performances of instrument (energy range, energy resolution, nuclear charge resolution, et al.) were determined by numerical modeling technique. Comparison of this instrument with other ones from point of view of the possibility of charge state study was fulfilled.

This paper describes the functional characteristic of the central processor module, which will be designed and can be used for gamma-ray Telescope in gamma-astronomical observatory and in acceleration high energy physics. As part of the installation will be Scientific Data Acquisition System (SDAS), one of the main modules will be developed central processor module MFSDAS (Module For Scientific Data Acquisition System). The module MFSDAS belongs to computer facilities and can be used for creation of digital computer systems, which are carrying out real time data receiving by high speed Serial RapidIO bus, preprocessing of the signals (the space-time spectral analysis, the frequency ranges formation, the filtration and threshold detection), and also secondary, tertiary and general information processing including data exchange with other devices and systems. Its description is presented in this paper. The main functions to be performed by the MFSDAS module: acceptance of scientific data from the switch module SpaceWire; execution of the functions of central processor (the management of exchange of scientific and control data between modules of the SDAS; the SDAS with scientific equipment and platforms); Serial RapidIO (SRIO) commutation channels; and as an option - data transmission to the Earth station equipment.

We propose a unified model of primordial black holes and soliton dark matter formation. Dynamic of spherically symmetric clumps of scalar field is considered in Newtonian approximation. The formation of hidden mass of the Universe is discussed. Numerical solution of the system of interacting scalar and gravitational fields is used to obtain the mass of a clumps.

The scientific apparatus “Gamma-400” designed for study of hadron and electromagnetic components of cosmic rays will be launched to elliptic orbit with an apogee of about 300 000 km and perigee of about 500 km. Such a configuration of the orbit allows it to cross periodically the radiation belt and the outer part of magnetosphere. We discuss the possibility to use hybrid pixel detecters based on the Timepix chip and semiconductive sensors. Due to high granularity of the sensor (pixel size is 55 mkm) and possibility to measure independently an energy deposition in each pixel such compact and lightweight detector installed on board of “Gamma-400” could be a unique instrument for study of spatial and time structure of electron and proton components of the radiation belt.

The results of low-energy charged particles passage through GAMMA-400 gamma-telescope thermal insulation and two-layer plastic scintillation detectors used as anticoincidence shield are presented. An existing GEANT4 GAMMA-400 model is used. Effects of several various types of thermal insulation on charged particle passage are investigated. These data will be used to determine the effect of low-energy charged particles flux on GAMMA-400 gamma-quanta registration capabilities, as sufficiently large energy deposition in two-layer plastic anti-coincidence scintillation detectors can interfere with high-energy particle registration and identification.

The GAMMA-400 gamma-ray telescope is intended to measure the fluxes of gamma-rays and cosmic-ray electrons and positrons in the energy range from 100 MeV to several TeV. Such measurements concern with the following scientific tasks: investigation of point sources of gamma-rays, studies of the energy spectra of Galactic and extragalactic diffuse emission, studies of gamma-ray bursts and gamma-ray emission from the Sun, as well as high precision measurements of spectra of high-energy electrons and positrons. Also the GAMMA-400 instrument provides the possibility for protons and nuclei measurements up to knee. But the main goal for the GAMMA-400 mission is to perform a sensitive search for signatures of dark matter particles in high-energy gamma-ray emission. To fulfill these measurements the GAMMA-400 gamma-ray telescope possesses unique physical characteristics in comparison with previous and present experiments. The main strength of the GAMMA-400 instrument is its expected excellent angular and energy resolution for gamma rays above 10 GeV. The GAMMA-400 experiment will be installed onboard of the ’Navigator’ space platform, manufactured by the NPO Lavochkin Association, able to accommodate high mass - large volume scientific payload. The expected orbit of the payload will mean that observations will not suffer disruption from Earth occultation hence allowing for deep observations of the sources of interest.

GAMMA-400 (Gamma Astronomical Multifunctional Modular Apparatus) will be the new generation satellite g-observatory. Gamma-telescope GAMMA-400 consists of anticoincidence system (top and lateral sections - ACtop and AClat), the converter-tracker (C), time-of-flight system (2 sections S1 and S2), position-sensitive calorimeter CC1 makes of 2 strips layers and 2 layers of CsI(Tl) detectors, electromagnetic calorimeter CC2 composed of CsI(Tl) crystals, neutron detector ND, scintillation detectors of the calorimeter (S3 and S4) and lateral detectors of the calorimeter (LD). All detector systems ACtop, AClat, S1-S4, LD consist of two BC-408 based sensitive layers of 1 cm thickness each. Three apertures provide events registration both from upper and lateral directions. The main aperture provides the best angular (all strip layers information analysis) and energy (energy deposition in the all detectors studying) resolution. Gamma-telescope GAMMA 400 is optimized for the gamma-quanta and charged particles with energy 100 GeV detection with the best parameters in the main aperture. Triggers in the main aperture will be formed using information about particle direction provided by time of flight system and presence of charged particle or backsplash signal formed according to analysis of energy deposition in combination of both layers anticoincidence systems АСtop and AClat individual detectors. In the additional aperture the particles identification is provided by analysis of signals corresponding to energy deposition in the individual detectors S2, S3 and fast signals from CC1 individual detectors discriminators. Low energy (0.2 - 10 MeV) in the lateral aperture photons recognizing by using simple anticoincidence signals from the individual detectors of LD. Gamma-quanta of higher energies are identified using energy deposition in the individual detectors of S3, S4, LD and fast signals from CC2 individual detectors discriminators. The results of anticoincidence system individual detectors thresholds are discussed for the main, additional and lateral apertures.

A description of the control and data transfer management system for scientific apparatus involved in the GAMMA-400 space project is given. The technical capabilities of all specialized equipment to provide the function of the scientific instrumentation and satellite support systems are unified in a single structure. The correctness of the proposed and implemented structure has been verified by the operation of the prototype of GAMMA-400 scientific complex. Control of the scientific instruments is maintained using one-time and program pulse commands, as well as program commands, which are transmitted via onboard control units and scientific data acquisition system. Up to 100 GByte of data per day can be downlinked to the ground control stations.

The characteristics of reliable fault-tolerant very large scale integration (VLSI) technology designed by SRISA for the developing of computation systems for space applications are considered. The scalable net structure of SDAS based on Serial RapidIO and SpaceWire interfaces including real-time operating system BAGET is described too.

Electron bursts are well-known phenomena of fast increase in particle fluxes in near-Earth space. Powerful local geophysical events like earthquakes or thunderstorms can induce precipitation of electrons with defined energy spectrum from radiation belt, which would be registered as fast increase in particle count rate on board the low orbit satellite. The process of longitudinal drift of precipitated relativistic electrons to the geographical east gives opportunity to detect burst in any point of L-shell around the globe. Electrons with different energies drifts with different velocities. Study of energy spectrum change in time of the detected burst gives information required to determine distance between location of electron precipitation and its registration as burst on board the satellite. Mixing of background albedo electrons with burst electrons and low total statistics of registered particles leads to high complexity of this type of analysis on experimental data with traditional methods. An analytical methods based on robust regression analysis was introduces for processing of data with high level of experimental uncertainty. Results of comparison between various data analysis methods in application to study of spatial and energy characteristics of relativistic electron bursts in the Earth magnetosphere are presented in this work. Numerical modeling of local relativistic electron precipitation with albedo electron fluxes and data from satellite experiments ARINA (on board the Resurs-DK1) and VSPLESK (on board the International Space Station) are used. Robust methods proved to be optimal for data analysis of energy spectrum evolution in time for search of zones of local radiation belt disturbances.

The main structure of the cosmic gamma-ray telescope GAMMA-400 which currently being in ground testing mode suggests the using of the system of fast two-layer scintillation detector for electromagnetic showers detection. This article will describes a basic method and shows a basic scheme of the ground testing measurement. Also it contains the main result reached by this test.

We describe a promising method for measuring the total dark matter mass near a supermassive black hole at the Galactic center based on observations of nonrelativistic precession of the orbits of fast S0 stars. An analytical expression for the precession angle has been obtained under the assumption of a power-law profile of the dark matter density. The awaited weighing of the dark matter at the Galactic center provides the strong constraints on the annihilation signal from the neuralino dark matter particle candidate. The mass of the dark matter necessary for the explanation of the observed excess of gamma-radiation owing to the annihilation of the dark matter particles has been calculated with allowance for the Sommerfeld effect.

We are going to show that any conventional decaying dark matter model, providing an explanation of cosmic antiparticle excess observed by PAMELA and AMS-02, inevitably faces the contradiction with isotropic diffuse gamma-ray background, measured by FERMI/LAT.

As we are going to show, some self-interacting dark matter models may provide an intriguing solution to the "cosmic antiparticle excess vs. isotropic diffuse gamma-ray background" problem.

We consider a model with a real scalar field with polynomial selfinteraction of the $4^{\text{th}}$ power and a coupled scalar triplet. We demonstrate that there is an analytical solution in the form of domain wall with coupled localised configuration of the scalar triplet. We analyse this new solution and also discuss orientational and translational moduli of the configuration.

We study excitations of solitary waves - the kinks - in scalar models with degree eight polynomial self-interaction in $(1+1)$ dimensions. We perform numerical studies of scattering of two kinks with an exponential asymptotic off each other and analyse the occurring resonance phenomena. We connect these phenomena to the energy exchange between the translational and the vibrational modes of the colliding kinks. We also consider the interaction of two kinks with power-law asymptotic; the latter leads to a long-range interaction between the two kinks.

Application Specific Integrated Circuits (ASICs) are one of the key complex technologies available to detector designers. A number of factors make ASICs essential to Particle Physics and Astrophysics. These include: integration scale, low power dissipation, radiation tolerance. In order to make possible future experiments in the intensity, cosmic, and energy frontiers ASICs should provide new level of functionality at a new set of constraints and trade-offs, like low-noise high-dynamic range amplification and pulse shaping, high-speed waveform sampling, low power digitization, fast digital data processing, serialization and data transmission. All components (chips) should be radiation tolerant and allow minute almost 3D assemblies. The talk presents overview of the state of the art and trends in nowadays chip design, basing partially our ASIC lab experience.

Abstract — An all-digital phase-locked loop (ADPLL) was implemented in 180 nm CMOS technology. The proposed ADPLL uses a novel digitally controlled oscillator to achieve 1 ps resolution. The pure digital phase locked loop is attractive because it is less sensitive to noise and operating conditions than its analog counterpart. The proposed ADPLL can be easily ported to different process as a soft IP block, making it very suitable for system-on-chip applications.

The development architecture of a multichannel data-driven ASIC is presented. It provides the selection of useful events at an early stage of reading out detector signals. The architecture is based on fast cross-point switches of analog signals, followed by their digitization by a limited set of ADCs and high-speed output data serialization.

In the large-scale high energy physics and astrophysics experiments multi-channel read-out application specific integrated circuits (ASICs) are widely used. The ASICs for such experiments is a complicated system, which usually includes both analog and digital building blocks. A trend to a complication of the system architecture, increase of the channels and building blocks amount in the chip is required to the proper methodological approach to the system design. The paper presents the mixed-signal top to bottom design flow of the ASICs for high energy physics and cosmic rays experiments. This flow was successfully embedded to the development of the read-out ASIC prototype for the muon chambers of the CBM experiment. The approach was approved in UMC CMOS MMRF 180 nm process. The design flow permits to analyze the mixed-signal system operation on the different levels: functional, behavioral, schematic and post layout including parasitic elements. The proposed design flow allows reducing the simulation period and eliminating the functionality mismatches on the very early stage of the design.

Problems of scientific devices control (for example, fine control of measuring paths), collecting auxiliary (service information about working capacity, conditions of carrying out experiment, etc.) and preliminary data processing are actual for any space device. Modern devices for space research it is impossible to imagine without devices that didn't use digital data processing methods and specialized or standard interfaces and computing facilities. For realization of these functions in "GRIS" experiment onboard ISS for minimization of dimensions, power consumption purposes, the concept "system-on-chip" was chosen and realized. In the programmable logical integrated scheme by Microsemi from ProASIC3 family with maximum capacity up to 3M system gates, the computing kernel and all necessary peripherals is created. In this paper we discuss structure, possibilities and resources the service telemetry and control device for "GRIS" space experiment.

Silicon photomultipliers (SiPM) are very promising semiconductor photon sensitive devices with high gain. However, the possibility of using SiPMs in some areas is limited by radiation tolerance. Synopsys TCAD software allows simulating of microelectronic devices and their physical characteristics. Simulating of manufacturing technology of SiPMs has been made. Experimental samples were produced and then irradiated with different doses of X-rays with energy E≈12 keV. For the investigation of effects of radiation IV curves of devices were measured before and after irradiation and compared with results obtained from simulation. Work has been partially supported by Megagrant 2013 program of Russia, agreement N14.A12.31.0006 from 24.06.2013.

Despite several advantages of Silicon Photomultipliers (SiPM) over Photomultiplier Tubes (PMT) like the increased photon detection efficiency (PDE), the compact design and the insensitivity to magnetic fields, the dark count rate (DCR) of SiPM is still a large drawback. Especially concerning applications with the need of large photosensitive areas or applications for which cooling of the detector is not an option. Reducing the dark count rate of SiPM would lead to an enormous enhancement of the application range of this promising photo-detector. The main goal of this work is to gain initial information on dark generation and identify the dominating contributions to dark currents. The chosen approach to do so, is to extract characteristic activation energies of the contributing mechanisms from temperature dependent investigations of dark currents and DCR. In this talk, first steps towards the development of a reliable method for the analysis of dark currents and dark events are presented.

Geiger discharge for a single cell and real SiPMs for under- and oversaturation light intensities has been investigated. It has been shown that not only signal amplitude but even signal charge rises with increasing of light intensity for single SiPM cell illuminated by high intensity light flash for constant applied overvoltage. This effect can be explained by creation of multiple avalanche starting points inside of a SiPM cell which leads to the development of multiple avalanches inside of the cell and thus to a higher discharge current when compared with the case of a single avalanche per cell. Due to this effect a real SiPM device consisting of many connected together cells and illuminated by high light intensity pulse produces a signal with amplitude that is higher then A1*N, where A1 – one-cell signal amplitude for low light conditions, N - total number of cells inside the SiPM.

The scintillator tiles with direct readout by silicon photomultipliers (SiPM) have been studied. The impact of the surface in front of the SiPM on the light yield and its uniformity has been studied. The different geometries, including geometries with a dimple in front of the SiPM were studied. The tiles with the optimal dimple design show the quality of response comparable to the tiles with fiber readout. The direct-readout approach provides a reasonable way for the construction of supermultichannel calorimeters.

To determine the depth of the area of radiopharmaceutical accumulation a method of simultaneous recording of two lines of gamma rays of different energies and quantitative comparison of the intensity of these lines on the surface of the patient's body is provided. Since the coefficient of linear absorption of gamma radiation in the medium depends not only on the characteristics of the medium, but also on the gamma radiation energy, the intensity of gammas of different energies is attenuated differently after passing through the same absorber layer (soft tissues). Thus, the quantitative comparison of the relative intensities of gamma lines on the surface of the patient's body allows to determine the depth of area of the accumulation of the radiopharmaceutical. The result is achieved by analyzing the energy spectrum of the source, obtained with a scintillation detector or a semiconductor spectrometer, by the quantitative analysis of the absorption peaks of the radioisotope. The most widely used medical radioisotope technetium-99m has two gamma-lines - 140 keV and 18 keV, which allows one to apply the proposed method to search for the sentinel lymph nodes and non-palpable malignant tumors in the soft tissues.

New generation of detectors for nuclear medicine will be based on Silicon Photomultipliers (SiPM's) due to their high gain, compact size, low weight and low operating voltage. The one main problem of SiPM's is presence of noise factors such as dark count rate, crosstalk and afterpulses. In such conditions it needs to develop the algorithm of positioning reconstruction allows to reach spatial resolution better than 3 mm. The last obtained results will be presented.

The utilization of silicon photomultipliers (SiPM) in the detection module opens up a new possibilities of using a gamma camera. Two prototypes of gamma camera were developed. In the first prototype takes place a direct reading of monolithic scintillator NaI(Tl) using SiPM matrix and signal digitizing from this matrix utilizing a multichannel ASIC Maroc 3. In the second prototype between the scintillator NaI(Tl) and silicon photodetectors orthogonally related wavelength shifting fibers (WLS) are placed reducing the number of photodetectors. Study of prototypes is required for calibration of simulation programs which allow to estimate expected spatial and energy gamma-camera resolution. Dark rate, crosstalk, afterpulsing give rise of noise-factor which violates initial photostatistics. Thus correct estimation of initial photons produced by gammas is a key question for carriing out of simulation.
