Japan Aerospace Exploration Agency (JAXA), Online meeting), Spacecrafts operated the outside of geo magnetosphere are irradiated solar protons directly. Therefore, it is important to investigate the charging phenomenon of insulation materials under a proton beam irradiation. In this study, we focused on the internal charge accumulation during proton beam irradiation of insulation materials. We developed the electrode system to measure the charge distribution from the surface to the bulk of the sample. From the results, it observed that the amount of charge accumulation is larger 3.4 times than the results of using the general electrode system and the surface potential is 4.4 kV. These results suggest the possibility of discharge at the spacecraft operating environment., 形態: カラー図版あり, Physical characteristics: Original contains color illustrations, 資料番号: AA2030009008, レポート番号: JAXA-SP-20-007}, pages = {53--56}, publisher = {宇宙航空研究開発機構(JAXA), Japan Aerospace Exploration Agency (JAXA)}, title = {陽子線照射されたフッ素系絶縁材料の電荷蓄積特性}, volume = {JAXA-SP-20-007}, year = {2021} }
