要約(英語): Surface materials of spacecraft operated in low and medium earth orbits, such as positioning satellite and earth observation satellite, are charged and discharged duet to radio-active rays, such as electrons and protons. Such the electro-static discharge is one of the origin of satellite operation anomaly. Therefore, in this study, we focus the FEP (fluorinated-ethylene-propylene copolymer) irradiated by proton and measure the space charge distribution using newly developed on-site space charge measurement system which can measure space charge accumulation during proton irradiation. We were able to get the result that positive charges were accumulated and saturated during irradiation. After saturation, the accumulated positive charges in the bulk were decreased during irradiation.
