Abstract

A method is described that allows the trapping charge kinetics in insulating materials during their electron irradn. in a scanning electron microscope (SEM) to be studied and the total trapped charge to be evaluated. The method consists in analyzing the leakage and the displacement currents measured simultaneously, during and after irradn., using an arrangement adapted to the SEM. The dynamic trapping properties of glass-ceramic are investigated and the time consts. for charging and discharging processes are evaluated. By correlating the leakage and displacement currents, the total electron yield ? during irradn. is also detd.
