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...

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...

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....

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...

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...

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...

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...

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.
