Abstract :
In a number of polymer electrets, radiation-induced conductivity (RIC) and its time and space dependence were investigated. Electron-transmission experiments yielded the initial deposition profiles; measurements of the rear-electrode voltages during irradiation with a monoenergetic electron beam permitted determination of the time and the dose-rate dependence of the RIC. From these data, the space-charge and field profiles, and their temporal variations, were calculated on the basis of a newly developed "trapezoid" model for the spatial profile of the RIC.
