The future space-based GAMMA-400 mission is intended for direct gamma- and cosmic-ray observations in the highly elliptic orbit during 7-10 years. GAMMA-400, currently developing gamma-ray telescope, will observe energy range from ∼20 MeV to several TeV some regions of Universe (such as Galactic Center, Fermi Bubbles, Crab, Cygnus, etc.) with unprecedented angular (∼0.01° at Eγ = 100 GeV) (∼1% resolutions better than Fermi-LAT, well ground telescopes, by a factor 5-10. also study cosmic rays...
The future space-based GAMMA-400 gamma-ray telescope will be installed on the Navigator platform of Russian Astrophysical Observatory. A highly elliptical orbit provide observations for 7-10 years many regions celestial sphere continuously a long time (~ 100 days). measure fluxes in energy range from ~ 20 MeV to several TeV and electron + positron up TeV. have an excellent separation gamma rays background cosmic electrons positrons protons unprecedented angular 0.01° at E γ = GeV) 1%...
Abstract The GAMMA-400 gamma-ray telescope is planned for the launch at end of this decade on Navigator service platform designed by Lavochkin Association an elliptical orbit with following initial parameters: apogee ~300000, a perigee ~500 km, rotation period ~7 days and inclination 51.4°. apparatus expected to operate more than 5 years, reaching unprecedented sensitivity search dark matter signatures study unresolved so far unidentified sources. An electronics system, which consists 14...
Abstract The GAMMA-400 project will be the new generation of satellite gamma-observatory. space-based gamma-ray telescope represents core scientific complex intended to perform a search for signatures dark matter in cosmic gamma-emission, measurements diffuse gamma-emission characteristics, investigation extended and point sources, studying high energy component bursts solar flares emission. Four fast plastic sub-detectors are included trigger logic main aperture. This aperture expected...
The currently developing space-based gamma-ray telescope GAMMA-400 will measure the and electron + positron fluxes using main top-down aperture in energy range from ~20 MeV to several TeV a highly elliptic orbit (without shading by Earth outside radiation belts) continuously for long time. instrument provide fundamentally new data on discrete sources, bursts (GRBs), sources propagation of Galactic cosmic rays signatures dark matter due its unique angular resolutions wide range. consists...
The upcoming GAMMA-400 experiment will be implemented aboard the Russian astrophysical space observatory, which operating in a highly elliptical orbit over period of 7 years to provide new data on gamma-ray emissions and cosmic-ray electron + positron fluxes, mainly from galactic plane, Galactic Center, Sun. main observation mode continuous point-source mode, with duration up ~100 days. telescope study high-energy several TeV electrons positrons 20 TeV. have high angular resolution, energy...
Abstract A new method of high-energy gamma ray incident direction reconstruction is developed for gamma-ray detectors with multilayered converters. The uses data from converter and, if available, position-sensitive calorimeter to reconstruct an electromagnetic cascade axis and determine the a primary gamma. For first time find point intersection line convertor plane, median energy deposit in sensitive plane used. Applied, example, GAMMA-400 space-based telescope this allowed achieve angular...
