A wire ion plasma electron gun as an X-ray source for preionizing-discharge
-excited KrF laser has been built and the secondary emission electron beam
flux up to a relatively low anode voltage of 6 kV has been calculated and m
easured. Aluminum and lithium targets are irradiated by an e-beam-pumped Kr
F laser and the plasma flux of each has been obtained. (C) 1999 Elsevier Sc
