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.
