Swa. Gielkens et al., A LONG-PULSE 300 KEV ELECTRON-GUN WITH A PLASMA CATHODE FOR HIGH-PRESSURE GAS-LASERS, Review of scientific instruments, 67(7), 1996, pp. 2449-2452
The design and main features of a plasma cathode electron gun for high
-pressure gas lasers are discussed. The mesh plasma cathode in combina
tion with a low-pressure gas discharge was used for the formation of a
large cross-section (55X4 cm(2)) electron beam with emission current
densities up to 1.7 A/cm(2), accelerating voltages up to 300 kV, and a
pulse length of 20 mu s (full width at half maximum). (C) 1996 Americ
