Abstract

Charge accumulating process in PMMA under electron beam irradiation was observed using the PIPWP method. To observe the characteristics of the charging process under irradiation, the apparatus for the PIPWP method has been modified. Using the improved system, a real-time measurement of charging process in PMMA was carried out under electron beam irradiation for 5 minutes. The accumulation process of the electrons injected into PMMA was clearly observed during the electron beam irradiation. From the obtained charge distribution, the change of the electric field and the potential distributions were also calculated. Furthermore, a decay process of the charge distribution after irradiation was observed
