Description

technical field [0001] The invention relates to the technical field of high-energy particle detection, in particular to a method and system for evaluating the performance of a high-energy particle detector. Background technique [0002] The high-energy particle radiation in near-Earth space is the main parameter of geophysical field satellite detection. It mainly uses the high-energy particle detector carried by the satellite to measure the energy, flux, and throwing angle of high-energy particles. Before the launch of the satellite, a ground calibration test will be carried out on the performance of the high-energy particle detector, mainly through the ground beamline method to effectively verify its energy linearity, detection efficiency, and geometric factors. After the satellite is in orbit, it is necessary to regularly evaluate the performance of the detector and make necessary parameter adjustments to obtain the best detection results. However, since general detectors...
