FIT will consist of two arrays of Cherenkov radiators (T0+ ) and a large segmented scintillator ring (V0+). FIT will serve as the mai n luminometer\, as well as the detector which will determine collision tim e\, multiplicity\, centrality\, and reaction plane in ALICE during Runs 3 and 4. Among the many challenges of this project are: a high dynamic range (0.4 to 250 MIP (minimum interaction particle) amplitude for T0+\, 0.5 to 600 MIP amplitude for V0+)\, operation with the sustained bunch crossing of 25 ns\, time resolution below 50 ps\, signal processing and trigger gen eration within 205 ns. Light generated in the scintillators of the V0 will be detected by 48 Hamamatsu fine mesh 2” PMTs. The Cherenkov radiators will be coupled to 52 modified Planacon light sensors. The photocathode si ze of XP85012/FIT-Q is 53x53 mm2. The 64 anodes at the base of a chevron-s haped assembly of MCP plates are divided into 4 equal sectors matching the radiator quadrants. To reach the required lifetime and dynamic range\, Pl anacons will operate at the output amplitude of 10 mV/MIP (charge 0.63 pC/ MIP) requiring special cabling and low-noise fast electronics. The time i nformation will be extracted from a CFD and digitized with the accuracy of better than 50 ps over the entire dynamic range. The input charge will be integrated and measured by an ADC. The first prototype of a Cherenkov mod ule and the full chain of front-end electronics were installed inside of t he ALICE magnet and are part of the Run 2 data collection since 2016. \nTh is work was supported by INR RAS and NRNU MEPhI within the Russian activit ies in the ALICE upgrade and by the Ministry of Education and Science of R ussian Federation\, contract No14.610.21.0003.\n\n[1] W.H.

For LHC Phase-2\, t he instantaneous luminosity delivered to the experiment will reach $5\\tim es10^{34}$ cm$^{-2}$s$^{-1}$\, resulting in high particle fluxes that requ ires the detectors to be upgraded. The forward regions\, corresponding to the endcaps of the detectors\, are the most affected parts. In the CMS exp eriment\, to cope with the higher event rates and larger radiation doses\, triple-layer Gas Electron Multipliers (GEM) will be installed in the muon endcaps. Triple-GEM chambers will complement the existing Cathode Strip C hambers\, leading to a better identification of the muon tracks and a redu ction of the trigger rate due to the suppression of fake candidates. In ad dition\, the forward coverage will be further extended.\nFor the first dis k of the muon endcaps\, 144 GEM chambers are being built in production sit es spread in 7 different countries around the world. For the first time\, such detectors will have large sizes of the order of $1$-$2$ m$^2$\, thus high requirements on the uniformity across the detector are needed.

It consists of 8 layers of altog ether ∼900 double sided silicon micro strip sensors. Limited mechanical precision(>100μm) during the mounting\, temperature differences result in misalignment to the detector component positions.

The sensitivity required by future neutrino physics implies unpre cedented detector masses\, for which traditional LAr TPC designs face chal lenges e.g. due to the long drift distances of O(10m). In order to efficie ntly drift ionisation electrons\, very High Voltage (HV) and LAr purity ar e required\, which comes along with risks of HV breakdowns with huge power dissipations.\nTo address these issues\, the ArgonCube Collaboration deve loped a novel generation LAr TPC design\, segmenting the total detector vo lume into a number of electrically and optically isolated TPCs sharing a c ommon cryostat. For the charge readout\, a pixelated anode plane is employ ed\, providing unambiguous 3D event reconstruction. To minimize inactive a nd dense material within the TPC a new technology is used for field shapin g\, replacing the classical field cage by a resistive field-shell. In the case of HV breakdown the continuous resistive shell reduces power dissipat ion. The scintillation light readout is achieved by large dielectric plane s inside the field-shell allowing for an efficient detection of prompt sci ntillation light and improved particle identification and trigger efficien cy.

Fo r these reasons\, next generation missions are planning to replace PMTs wi th SiPMs. \nWe tested a prototype plastic scintillator tile\, equipped wit h a set of SiPMs and studied its response to a beam of electrons and pions at CERN. We used Near Ultraviolet (NUV) SiPMs of 1x1 mm$^2$ and 4x4 mm$^2 $ area\, placed along the edges of the tile. The tile was irradiated in di fferent positions in order to study the dependence of the collected light on the impact point of the beam particles.\nWe also varied the energy of t he beam in order to study how this parameter affects the amount of collect ed light.\n\nhttps://indico.particle.mephi.ru/event/22/contributions/1136/ LOCATION:Hotel Intourist Kolomenskoye 4* Moskvorechye 2 hall URL:https://indico.particle.mephi.ru/event/22/contributions/1136/ END:VEVENT BEGIN:VEVENT SUMMARY:Creation of the "Carpet-3" multipurpose shower array for search o f diffuse gamma radiation whith energy E>100 TeV DTSTART;VALUE=DATE-TIME:20181023T134500Z DTEND;VALUE=DATE-TIME:20181023T140000Z DTSTAMP;VALUE=DATE-TIME:20260313T082046Z UID:indico-contribution-140-1134@cern.ch DESCRIPTION:Speakers: Aleksandr Kudzhaev (Baksan Neutrino Observatory\, IN R of RAS)\nAn experiment for measuring the flux of cosmic gamma rays with energy above 100TeV is currently being prepared at the Baksan Neutrino Obs ervatory of the Institute for Nuclear Research\, Russian Academy of Scienc es. At present the plastic scintillation counters with a total continuous area of 410m^2 are installed in the muon detector (MD) underground tunnels \, and they are totally equipped with electronics. Six modules of shower d etectors(out of twenty planned to be installed) have been already placed o n the surface of the MD absorber. In each of them are placed on 9 standard plastic scintillation counters with an area of 1m^2 each. These modules a re by part ground of “Carpet-3” shower array. It is also placing and a rrange of recording apparatus for this array. The calculations are showed that the “Carpet-3” shower array will have the best sensitivity to the flux of primary gamma rays with energy TeV and will be quite competitive in gamma ray astronomy in such energies.\n\nhttps://indico.particle.mephi .ru/event/22/contributions/1134/ LOCATION:Hotel Intourist Kolomenskoye 4* Moskvorechye 2 hall URL:https://indico.particle.mephi.ru/event/22/contributions/1134/ END:VEVENT END:VCALENDAR
