Fermi Gamma-ray Space Telescope

Gamma-ray performance of the GAMMA-400 detector

Paolo Cumani

Abstract:

GAMMA-400 is a new space mission, designed as a dual experiment, capable to study both high energy gamma-rays (from ~100 MeV to few TeV) and cosmic-rays (electrons up to 20 TeV and nuclei up to ~10^15 eV). The full simulation framework of GAMMA-400 is based on the Geant4 toolkit. The details of the gamma-ray reconstruction pipeline in the three main instruments (Tracker, Imaging Calorimeter, Homogeneous Calorimeter) as well as the trigger simulation will be outlined. The performance of GAMMA-400 (PSF, effective area, energy resolution and sensitivity) have been obtained using this framework. The most updated results on them will be shown.
