Experimental Study of Transient Effects in Dielectric Materials Caused by Electron Irradiation.
Abstract
Voltage pulses in capacitors and insulated wires during low energy electron irradiation were studied. Various dielectric materials (polyethylene terephthalate, polytetrafluoroethylene, polystyrene, ceramic, polypyromellitimide, regenerated cellulose, polyvinyl alcohol, a copolymer of polyvinyl chloride and polyvinylidene chloride, mica paper, and silicone impregnated mica paper) were tested over a range of incident electron kinetic energies, temperatures, and dose rates. The number of pulses was found to vary with the incident electron kinetic energy. Temperature also had a profound effect on the number of pulses. Irradiation at low temperatures resulted in a greater number of pulses. Some of the present results are compared with results obtained from previously published work on the x ray induced conductivity in dielectric materials.
