Title: Characteristics of space charge in PMMA after electron beam radiation
Abstract: Space charge was introduced into the PMMA (polymethyl methacrylate) samples by electron beam. The effect of electron beam on the conductivity and the permittivity of the PMMA sample were investigated, and the breakdown of the samples during charge detrapping was also studied. The experimental results show that not only space charge injection but its detrapping also makes samples breakdown. The dynamics of injected charges in the radiated PMMA samples and the mechanism of the breakdown resulted from the rapid discharge are discussed.
