抄録（英）
Effect of cyclic electron irradiation on dielectric film for spacecraft is investigated experimentally because it may cause cumulative charge deposition onto the film surface. 60sec and 30sec irradiation time, 90 min and 30 min interval 40keV and 20keV energy, irradiation are tested and the result indicates that the surface potential does not fall significantly as we expected. Results of volume resistivities just after each irradiation show that resistivity is unchanged during multiple irradiations and it is lower in the case of 30 min interval and 40keV energy case.
