“…Using the combined information from all GAMMA-400 detector systems, it is possible to reach an effective rejection of electrons from protons. The methods to separate electrons from protons presented in (Leonov et al, 2015) are based on the difference of the development of hadronic and electromagnetic showers inside the instrument. For the current physical scheme the rejection factor for vertical protons is ~10 4 (Leonov et al, 2019).…”

The future space-based GAMMA-400 gamma-ray telescope will be installed on the Navigator platform of the Russian Astrophysical Observatory. A highly elliptical orbit will provide observations for 7-10 years of many regions of the celestial sphere continuously for a long time (~ 100 days). GAMMA-400 will measure gamma-ray fluxes in the energy range from ~ 20 MeV to several TeV and electron + positron fluxes up to ~ 20 TeV. GAMMA-400 will have an excellent separation of gamma rays from the background of cosmic rays and electrons + positrons from protons and an unprecedented angular (~ 0.01° at Eγ = 100 GeV) and energy (~ 1% at Eγ = 100 GeV) resolutions better than for Fermi-LAT, as well as ground-based facilities, by a factor of 5-10. Observations of GAMMA-400 will provide new fundamental data on discrete sources and spectra of gamma-ray emission and electrons + positrons, as well as the nature of dark matter.

The scientific goals of the GAMMA-400 space mission and the design of the new spacebased gamma-ray telescope GAMMA-400 are presented. GAMMA-400 is a dual experiment dedicated to the study of gamma rays and electrons, protons and nuclei. It has aimed to a broad range of scientific topics, such as search for signatures of dark matter, studies of Galactic and extragalactic gamma-ray sources, especially Galactic Center, Galactic and extragalactic diffuse emission, as well as high-precision measurements of cosmic rays spectra. GAMMA-400 will have the best parameters when measuring gamma rays: the angular resolution ∼0.01 deg. (at 100 GeV), the energy resolution ∼1% (at 100 GeV), and the proton rejection factor ∼10 6 and will be able to measure gamma-ray and cosmic-ray electron + positron fluxes in the energy range from 100 MeV to 20 TeV, as well as protons and nuclei up to the knee (10 15 -10 16 eV).
