抄録（英）
It has been reported that the MLI and OSR of spacecraft and the insulation layer of the wire harness are charged by high-energy charged particles such as electrons and protons, resulting in operational abnormalities due to electrostatic discharge. In this study, we measured space charge distribution during proton beam irradiation in order to understand the charge accumulation characteristics of space insulating materials by proton beam irradiation. As a result, positive charge accumulation was observed in the sample, and different charge accumulation tendencies were obtained in the proton passage region and the unreachable region. This elephant is thought to be caused by radiation-induced conduction with different origin in each region and the increase in conductivity, and was examined from the accumulated charge amount and distribution.
