[PCG24-16] Development of Geant4 application for particle detector design
Keywords:Geant4 simulation, Particle detector, Satellite instrument, Detector calibration
In this research, we developed a G-factor Analysis tool using Geant4 (GAG) simulation to make it easier to test the particle detector's characteristics. For easy operation, the GAG has two main features. The one is that GAG can be read the detector geometry from a CAD file which is difficult to adapt to Geant4 simulation. And the other is the automatic calculation of results such as detector's efficiency, G-factor, and spectral characteristics, etc. These features are based on the result of the calibration studies of the HEP instrument onboard the Arase satellite, which allows the GAG application to be used to determine the characteristics of the detectors as well as to perform the calibration.
Using these application's features, we examine the characteristics of particle detectors such as XEP and TENKOH, as well as HEP. The results of the simulation provide cross-calibration information. We report the preliminary result of these simulation results
