Abstract:

Experiments have been run and a comprehensive theoretical model developed which have enabled a more complete characterization of the ion plasma electron gun. The experiments provided important high current data on the operation of the gun and of the thin-wire discharges. The theoretical model included consideration of fifteen different reactions between helium atoms and ions and electrons and calculated the particle fluxes and the electric potential as a function of position in the high-voltage region. These calculated quantities described accurately the behavior of the gun at a beam voltage of 110 kV and enable a projection of operation of the e-gun at high voltages, such as 400 keV, with a beam current of 10 Asq cm where the gun will be useful to pump excimer lasers. A qualitative understanding was obtained of the transient behavior of both the e-gun and of the scaling properties of the thin-wire discharges.
