Advanced GAMMA-400 γ-ray telescope for recording cosmic γ rays with energies up to 3 TeV
The results of calculation and measurements performed on prototypes of the calorimeter, time-of-flight, and coordinate systems of the advanced GAMMA-400 γ-ray telescope, designed for studying diffuse cosmic γ rays and search for γ-ray lines arising after annihilation of neutralinos (dark matter particles), are reported.
