Abstract: The potential induced on the surface of a nonconducting ceramic during irradiation by an electron beam in the forevacuum pressure range (5–15 Pa) remains negative, but its absolute value is much smaller than the energy of accelerated electrons. The factors affecting the negative potential of a nonconducting ceramic target are determined. The evolution of the charge injected in the ceramic is analyzed by a numerical simulation.
