GAMMA-400 is a new space mission which will be installed on board the Russian space platform Navigator. It is scheduled to be launched at the beginning of the next decade. GAMMA-400 is designed to study simultaneously gamma rays (up to 3 TeV) and cosmic rays (electrons and positrons from 1 GeV to 20 TeV, nuclei up to 1015-1016 eV). Being a dual-purpose mission, GAMMA-400 will be able to address some of the most impelling science topics, such as search for signatures of dark matter, cosmic-rays origin and propagation, and the nature of transients. GAMMA-400 will try to solve the unanswered questions on these topics by high-precision measurements of the Galactic and extragalactic gamma-ray sources, Galactic and extragalactic diffuse emission and the spectra of cosmic-ray electrons + positrons and nuclei, thanks to excellent energy and angular resolutions.

Title: Status of the GAMMA-400 Project
Authors: A. M. Galper, O. Adriani, R. L. Aptekar, I. V. Arkhangelskaja, A. I. Arkhangelskiy, M. Boezio, V. Bonvicini, K. A. Boyarchuk, Yu. V. Gusakov, M. O. Farber, M. I. Fradkin, V. A. Kachanov, V. A. Kaplin, M. D. Kheymits, A. A. Leonov, F. Longo, P. Maestro, P. Marrocchesi, E. P. Mazets, E. Mocchiutti, A. A. Moiseev, N. Mori, I. Moskalenko, P. Yu. Naumov, P. Papini, P. Picozza, V. G. Rodin, M. F. Runtso, R. Sparvoli, P. Spillantini, S. I. Suchkov, M. Tavani, N. P. Topchiev, A. Vacchi, E. Vannuccini, Yu. T. Yurkin, N. Zampa, V. G. Zverev

The preliminary design of the new space gamma-ray telescope GAMMA-400 for the energy range 100 MeV - 3 TeV is presented. The angular resolution of the instrument, 1-2° at E{\gamma} ~100 MeV and ~0.01° at E{\gamma} > 100 GeV, its energy resolution ~1% at E{\gamma} > 100 GeV, and the proton rejection factor ~10E6 are optimised 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 high-precision measurements of spectra of cosmic-ray electrons, positrons, and nuclei.
