Abstract

When designing devices of modern gamma astronomy, one of the most important problems is achieving the maximum possible angular resolution. This study is devoted to the method for reconstructing the arrival direction of primary gamma-rays with energies E_γ > 10 GeV in the GAMMA-400 satellite experiment. By the example of the GAMMA-400 gamma telescope, the possibility of improving the angular resolution of gamma telescopes incorporating a "converter + calorimeter" system is shown. The dependence of the angular resolution on the step of silicon strips used to determine the coordinates of incident particles in the converter and calorimeter and the distance between the converter and calorimeter is analyzed.
