| Research Abstract |
Surface and volume resistivity of UV-irradiated or EB-irradiated insulator materials used for the artificial satellites were measured in vacuum condition. The measured materials are a glass which is used for the cover glass of solar panel and a polyimide film which is used for the thermal control material on the satellite. It was confirmed that the surface resistivity and volume resistivity had no difference regardless of UV or EB irradiation. But the chemical surface state of UV-irradiated polyimide film was changed according to irradiance level. The change in the surface state of UV-irradiated polyimide film was bigger than the EB-irradiated one.
