摘要

Advanced measurement techniques for charging in bulk of insulating materials irradiated by radioactive rays, especially electron beam or gamma ray, will be introduced. Using the techniques, so called PEA and PIPWP, charge distributions accumulating in the bulk of insulating materials arc measured precisely. These techniques arc originally developed for measurement of charge accumulation in insulating materials of high voltage devices such as cable insulating materials. On the other hand, there are many reports for accidents of spacecraft in space environment caused by the bulk charge accumulation due to the irradiation of high-energy cosmic ray. Unfortunately, there are many unknown parts concerning to the relationship between the charge accumulation in bulk of insulating materials have been left, while the experimentally measurement of charge distribution in bulk had been difficult. Therefore authors have tried to apply above techniques to measure the charge distribution in insulating materials irradiated by electron beam or gamma ray. In this paper, the principle of the measurement will be introduced at first, then some typical measurement results will be shown.
