Monte Carlo simulation of angular response of GRID detectors for GRID mission
Abstract The scientific observation of gamma-ray bursts (GRBs) paves the way towards unveiling a novel perspective of the dynamic universe. In the past few years, several nano-satellite (NanoSat) GRB observation missions were deployed, especially the Gamma-Ray Integrated Detectors (GRID) Mission which is currently constructing a constellation of NanoSats with more than ten compact gamma-ray detectors. Owing to the unpredictability of the time and location of GRBs, angular response of such compact detector is one of the most important aspects for not only the localization of GRBs but also the spectrum analysis of GRB events. This article presents a Monte Carlo framework for simulating the angular response of individual NanoSat in the GRID space mission and related experimental verification. Besides, the physical model constructed based on the simulated angular response in this article has been successfully applied to scientific analysis of multiple observed GRB events — GRB 230812B, GRB 210121A and GRB 220408B, and can be used for spatial localization of GRB events in the future.
