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...

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...

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...

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...

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.
