[GA285] A fast photon simulation algorithm for the DAMPE experiment


  • Simone GARRAPPA

Primary authors



We have implemented a fast simulation algorithm (FASTSIM) which can generate photon events from any astrophysical source and can process these events according to the DAMPE instrument response functions. The Galactic diffuse emission up to 10 TeV is evaluated with the DRAGON cosmic-ray propagation code, in which cosmic-ray interactions with the interstellar medium are described using the cross-sections from the FLUKA simulation toolkit. The FASTSIM tool can be interfaced with the instrument pointing history, which can be taken either from real DAMPE orbital data or from simulations. The tool will be used to evaluate the expected performance of DAMPE in the study of gamma-ray sources and its sensitivity to a possible dark matter signal in the gamma-ray channel.
