摘要

Equipment for measurement of internal charges in dielectric materials has been developed in order to apply it for spacecrafts as a real time charge monitoring system. A non-destructive and direct measurement technique, called PIPWP method, is utilized to observe charge distribution of dielectrics in bulk. This method also enables us to measure the charge accumulating process in real time. The measurement results clarified the charge accumulating/dissipating process in a PMMA film during/after electron beam irradiation for 5 minutes. The distributions of the electric field and the electric potential were also calculated. A spacecrafts' onboard charge monitoring system concept is outlined and it was found that we needed further modification to put it in practice.
