The GAMMA-400 gamma-ray telescope is designed to measure the fluxes of gamma rays and cosmic-ray electrons + positrons, which can be produced by annihilation or decay dark matter particles, as well survey celestial sphere in order study point extended sources rays, energy spectra Galactic extragalactic diffuse emission, bursts, emission from Sun. covers range 100 MeV 3000 GeV. Its angular resolution ~0.01 deg (E{\gamma} > GeV), ~1% 10 proton rejection factor ~10E6. will installed on Russian...
Gamma-telescope GAMMA-400 consists of anticoincidence system (polyvinylyltoluene BC-408 based top and lateral detector sections, the converter-tracker with thickness ∼1 X0 (where is radiation length), time-of-flight (two sections composed detectors 50 cm distance between), two calorimeters makes CsI(Tl) crystals (position-sensitive electromagnetic. Also it includes neutron detector, scintillation calorimeter, four calorimeter. The total calorimeter 25 or 1.2 λ0 for vertical incident...
The present design of the new space observatory GAMMA-400 is presented in this paper. instrument has been designed for optimal detection gamma rays a broad energy range (from ~100 MeV up to 3 TeV), with excellent angular and resolution. will also allow precise high statistic studies electron component cosmic multi TeV region, as well protons nuclei spectra knee region. address science topics, like search signatures dark matter, Galactic extragalactic gamma-ray sources, diffuse emission,...
The design of the new space-based gamma-ray telescope GAMMA-400 is presented. optimized for energy 100 GeV with best parameters: angular resolution ~0.01 deg, ~1%, and proton rejection factor ~10E6, but able to measure electron + positron fluxes in range from MeV 10 TeV. aimed a broad science topics, such as search signatures dark matter, studies Galactic extragalactic sources, diffuse emission, bursts, well high-precision measurements spectra cosmic-ray electrons positrons, nuclei.
The GAMMA-400 gamma-ray telescope with excellent angular and energy resolutions is designed to search for signatures of dark matter in the fluxes emission electrons + positrons. Precision investigations from Galactic Center, Crab, Vela, Cygnus, Geminga, other regions will be performed, as well diffuse emission, along measurements high-energy electron positron nuclei fluxes. Furthermore, it study bursts Sun during periods solar activity. range expected ~20 MeV up TeV energies gamma rays, 20...
The problem of electronic component unification at the different levels (circuits, interfaces, hardware and software) used in space industry is considered. task computer systems for purposes developing discussed by example scientific data acquisition system project GAMMA-400. basic characteristics high reliable fault tolerant chips developed SRISA RAS applicable computational are given. To reduce power consumption enhance reliability, embedded interconnect made hierarchical: upper level...
GAMMA-400 γ-ray telescope is designed to measure fluxes of γ-rays and the electron–positron cosmic ray component possibly generated in annihilation or decay dark matter particles; search for study detail discrete sources, examine energy spectra Galactic extragalactic diffuse γ-rays, bursts from active Sun. consists plastic scintillation anticoincidence top lateral detectors, converter-tracker, detectors time-of-flight system (TOF), two-part calorimeter (CC1 CC2), calorimeter, neutron...
Fermi-LAT has made a significant contribution to the study of high-energy gamma-ray diffuse emission and observation ∼3000 discrete sources. However, one third all sources (both galactic extragalactic) are unidentified, data on should be clarified, signatures dark matter particles in range not observed up now. GAMMA-400, currently developing telescope, will have angular (∼0.01° at 100 GeV) energy (∼1% resolutions 10-1000 GeV better than (as well as ground telescopes) by factor 5-10 observe...
