The development of the GAMMA-400 ?-ray telescope continues. The GAMMA-400 is designed to measure fluxes of ?-rays and the electron-positron cosmic-ray component possibly associated with annihilation or decay of dark matter particles; and to search for and study in detail discrete ?-ray sources, to measure the energy spectra of Galactic and extragalactic diffuse ?-rays, and to study ?-ray bursts and ?-rays from the active Sun. The energy range for measuring ?-rays and electrons (positrons) is from 100 MeV to 3000 GeV. For 100-GeV ?-rays, the ?-ray telescope has an angular resolution of ~0.01°, an energy resolution of ~1%, and a proton rejection factor of ~5 × 10<sup>5</sup>. The GAMMA-400 will be installed onboard the Russian Space Observatory.

Abstract
The development of the GAMMA-400 ?-ray telescope continues. The GAMMA-400 is designed to measure fluxes of ?-rays and the electron-positron cosmic-ray component possibly associated with annihilation or decay of dark matter particles; and to search for and study in detail discrete ?-ray sources, to measure the energy spectra of Galactic and extragalactic diffuse ?-rays, and to study ?-ray bursts and ?-rays from the active Sun. The energy range for measuring ?-rays and electrons (positrons) is from 100 MeV to 3000 GeV. For 100-GeV ?-rays, the ?-ray telescope has an angular resolution of ~0.01°, an energy resolution of ~1%, and a proton rejection factor of ~5 × 105. The GAMMA-400 will be installed onboard the Russian Space Observatory.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
