A full and customizable simulation of a scintillation tile equipped with SiPMs for Plastic Scintillator Detectors in the next generation of satellite experiments

Abstract We implemented a full and customizable simulation framework based on GEANT4 to investigate the performance of a segmented PSD made of scintillator tiles coupled to SiPMs. The purpose of this simulation is to study the effects of the scintillator optical properties and the coupling with SiPMs in order to be able to choose the best geometry of the tile and the best design for the SiPM-based readout system. We simulated a single tile equipped with SiPMs with the possibility to customize the tile and the SiPMs dimensions and position with respect to the tile facets. We will present the results of this simulation, together with the study of the scintillation photons collected by the SiPMs in terms of the spatial density of the detected photons and of their collection time.
