Area Electron Beam Emitting Device.
Abstract
One method of stabilizing high pressure CO2 and CO laser gas discharges is that of producing the ionization by an electron beam. An electron beam source is described which does not use a thermionic emitter but rather secondary emission from a cathode in a low pressure gas discharge. The work was primarily directed toward understanding a plasma discharge which will produce electron energies up to 150 kV and electron current densities up to 1 A/sq. cm for durations of the order of 20 microseconds. For voltages up to about 120 kV a pulse duration of 100 microseconds or longer is attainable without arcing.
