Spacecrafts sometimes have a serious damage due to the electrostatic discharge accident. It is said that the charge accumulation in dielectric materials irradiated by high energy particles in space environment causes the discharge accident. However, there remain many unknown factor about a charge accumulation in dielectric materials by irradiation of charged particle. Therefore, we need to measure the charge distribution in the bulk of dielectric materials. We have had many experiences to measure the charge distribution in dielectric materials under electron-beam irradiation. However, there are few measurement results of the proton-beam irradiated samples and we have to carry out a proton-beam irradiation in specially arranged equipment for proton beam irradiation. Therefore, we have been developing a compact bulk charge measurement apparatus for applying to several measurement environments in various irradiation chamber., 形態: カラー図版あり, 資料番号: AA0064382010, レポート番号: JAXA-SP-08-018}, publisher = {宇宙航空研究開発機構, Japan Aerospace Exploration Agency (JAXA)}, title = {プロトン照射絶縁材料における電荷蓄積特性}, volume = {JAXA-SP-08-018}, year = {2009} }
