This study especially has focused on a spacecraft charging accident caused by internal charge accumulation in dielectric materials irradiated by proton beam. The internal charge accumulation of those bulks measurement was carried out using Pulsed Electro-Acoustic (PEA) method. As the results, we obtained a positive charge accumulation in the bulk of samples after proton beam irradiation. However, it was not observed a positive charge accumulation that a quartz glass has an Al evaporated layer on the surface of proton beam irradiation side. Therefore, in this paper, we compare between the PEA's internal charge measurement results and energy band model because of we discus the charge formation mechanism in the bulk irradiated by proton beam., 資料番号: AA0049054030, レポート番号: JAXA-SP-05-008}, title = {内部帯電センサの研究:プロトン照射絶縁材料の帯電計測および解析}, year = {2006} }
