The interest in the charging of macroscopic particles of matter has grown in recent years. This is connected with the desire to accelerate macroscopic particles to high velocities with the goal of modelling the behavior of micrometeorites, and initiating thermonuclear fusion. In addition, charged macroscopic particles are used as fuel in reactive electrostatic motors. The means usually used in charging macroscopic particles impart to them a surface charge. The development of acceleration technology has made it possible, in recent years, to give a volume charge to dielectrics, through irradiation by fast electrons or gamma rays. This method allows one to charge the entire volume of a dielectric with cross-sectional area up to several square centimeters. The charge deposited within the dielectric by this method can be so large that discharge, or even spallation, sets in rapidly.
