一般注記Electrical charge accumulation characteristics in dielectric materials for a spacecraft panel have studied for understanding of spacecraft charging problem in high energy radiation environment. 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 PEA (Pulsed Electro-Acoustic) 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. Furthermore, we studied how to measure the secondary electron emission (SEE) of metal and insulating materials used for satellite thermal insulation or other such purposes. SEE yield measurement is very important for analyzing charge accumulation on the satellite surfaces due to the space environment because electron emission. Therefore, we tried to measure the SEE yield. In this report, we introduce the SEE yield measurement results of reference materials (Au, Ag and Quartz glass) and insulating materials. From those results, we discuss the characteristics of SEE that depend on each material.
