Preliminary studies regarding the interaction of intense short electron beams with different metallic targets are presented. The electron generator consists of a fast filamentary discharge in low- pressure gases. The filling gas is Helium, Argon, or Nitrogen at approximately 0.1 Torr pressure. The target might be easily changed. Also, the beam might be magnetically deflected in order to be properly directed. The interaction of the beam with different targets was investigated by means of a scanning electron microscope. The device is capable to drill holes of several tenths of microns in diameter in metallic targets.
