We have been researching space charge detection technology using photonic crystals. We have developed a fiber module incorporating a photonic crystal waveguide chip and have demonstrated space charge detection in air and at room temperature. This photonic charge sensor can be miniaturized, and since it uses only optical technology in the detection area, it is thought to be resistant to radiation and electrostatic discharge. Given these advantages, we aim to install this sensor on a spacecraft and use it to detect charged particles in space. Although we have succeeded in detecting space charges in a vacuum to date, it is necessary to investigate the response characteristics to cosmic radiation in order to improve the reliability of the sensor, calibrate the data, and optimize the design. In this study, we report on the effects of proton beam irradiation on the sensor module and its resistance.
