“…In agreement with previous works [7,8], the experimental results reveal that irradiation-induced defects play a major role in electron trapping, while the structural defects such as impurities contribute to the sample conductivity and lead to a release of the trapped charge.…”

“…This time decreases for glass, while it increases for quartz, with increasing voltage. The highest conductivity will lead to the shortest time to reach the saturation of trapped charge [7]. As regards the trapped charge, the experimental results clearly show that this charge increases slightly for the glass, while it increases significantly for quartz as the accelerating voltage increases.…”

The aim of this work is to study the electron irradiation behaviour of an insulating material surface using a scanning electron microscope (SEM). The charging phenomena caused in two kinds of insulating materials (quartz and glass) by continuous electron irradiation have been observed. The discharging phenomena following switching off of irradiation have also been studied. The trapped charge density is determined by using the so-called electrostatic influence method based on the measurement, during and after the irradiation, of the influence and leakage currents using an arrangement adapted to the SEM. The experimental results reveal that the behaviour under irradiation of glass is entirely different from that of quartz. The trapped charges are found to be different, and the dependence of charging on the primary beam energy is discussed.The charging and discharging time constants have been determined accurately, and their evolution versus the mean electron penetration depth is qualitatively explained. Moreover, the role of secondary electron emission in the regulation mechanism of charging is underlined.
