Simulation of DAMPE silicon microstrip detectors in the $\mathrm{Allpi}{\mathrm{x}}^2$ framework

Abstract

Silicon strip detectors have been widely utilized in space experiments for gamma-ray and cosmic-ray detections thanks to their high spatial resolution and stable performance. For a silicon micro-strip detector, the Monte Carlo simulation is recognized as a practical and cost-effective approach to verify the detector performance. In this study, a technique for the simulation of the silicon micro-strip detector with the $\mathrm{Allpi}{\mathrm{x}}^2$ framework is developed. By incorporating the electric field into the particle transport simulation based on Geant4, this framework could precisely emulate the carrier drift in the silicon micro-strip detector. The simulation results are validated using the beam test data as well as the flight data of the DAMPE experiment, which suggests that the $\mathrm{Allpi}{\mathrm{x}}^2$ framework is a powerful tool to obtain the performance of the silicon micro-strip detector.
