Research on Electron Irradiation Test of Si-PIN Detectors for Space Particle Monitor

Long term high energy electron irradiation may affect the performance of the Si-PIN Semiconductor Detector (SSD). In order to check the electronic radiation ability of the device, electron irradiation source was used to simulate space electron environment, and the irradiation experiments were carried out on the semiconductor detector. Experiment results show that under the radiation dose of 7.64×10¹⁴, the SSD's energy response capability had not changed, and the counting efficiency slightly decreased. As the radiation dose increased, the leakage current of the SSD increased, but the noise was relatively stable, and the performance of the detector did not affect the work index of the load.
