The present design of the new space gamma-ray telescope GAMMA-400 for the energy range 50 MeV - 3 TeV is presented. The proposed instrument has an angular resolution of 1-2 degrees at E(γ) ∼100 MeV and ∼0.01 degrees at E(γ) > 100 GeV and an energy resolution ∼1% at E(γ) > 100 GeV. By means of a deep segmented calorimeter high energy electron flux can be studied, with a proton rejection factor of about 106. The GAMMA-400 experiment is optimized to address a broad range of science topics, such as search for signatures of dark matter, studies of galactic and extragalactic gamma-ray sources, galactic and extragalactic diffuse emission, gamma-ray bursts, as well as highprecision measurements of spectra of high energy electrons, protons and nuclei up to the knee. © 2013 Elsevier B.V.

Abstract
The present design of the new space gamma-ray telescope GAMMA-400 for the energy range 50 MeV - 3 TeV is presented. The proposed instrument has an angular resolution of 1-2 degrees at E(γ) ∼100 MeV and ∼0.01 degrees at E(γ) > 100 GeV and an energy resolution ∼1% at E(γ) > 100 GeV. By means of a deep segmented calorimeter high energy electron flux can be studied, with a proton rejection factor of about 106. The GAMMA-400 experiment is optimized to address a broad range of science topics, such as search for signatures of dark matter, studies of galactic and extragalactic gamma-ray sources, galactic and extragalactic diffuse emission, gamma-ray bursts, as well as highprecision measurements of spectra of high energy electrons, protons and nuclei up to the knee. © 2013 Elsevier B.V.
