要約(英語): Spacecraft has been operatied in the radiation zone where it is directly exposed by electrons and protons. In such environment, a charging and a discharging phenomena occur in insulating materials on the surface of spacecraft. These phenomena may lead to the deterioration of the insulators and the malfunction of onboard equipments, and consequently they make the life time of spacecraft shorter. Therefore, for high reliability and long service life of the spacecraft, it is important to evaluate the characteristics of charging phenomena of insulating materials for spacecraft at the design stage. In previous research, we investigated electron beam irradiated ETFE (Ethylene-tetrafluoroethylene) and FEP (Fluorinatedethylene-propylenecopolymer), which are used for OSR (Optical Solar Reflector) and wire harness, to evaluate the charging properties of them by the irradiation of the electron. In the research, the space charge accumulation characteristics in the irradiated ETFE and FEP have been observed using PEA (pulsed electro-acoustic) method under high DC electric field. As the results, the generation of electron-hole pairs were confirmed in the electron beam irradiated materials. In this research, we tried to evaluate the dependences of the acceleration energy and irradiation time of the electron beam on the amount of electron-hole pair generated in the sample. As a result, we found that the amount of generated electron-hole pairs increased with increase of both acceleration energy and irradiation time.
