Paper Abstract

With multigap pseudo-spark chambers intense pulsed electron beams are generated by a low pressure discharge in different kinds of gases. The beams propagate in a self-focused manner through the low pressure gas. This depends on the influence of its own magnetic field and space charge neutralization. After a few millimeters the flight path of the beams hit metallic targets and drills holes of some tenths of millimeters in diameter. In principle the fact of drilling holes is not restricted to metallic materials. This is also possible into organic and inorganic insulators. The main applications for such beams therefore is high quality material processing. Furthermore it is shown to produce wideband soft X-rays. The option of postacceleration of such beams makes it attractive for future accelerators.
