Abstract
A new kind of electron gun is described which has produced 5-μs 
-beams at 130 keV and 2 A/cm2. Scaling estimates are presented which predict that this gun could operate at 400 keV and 10 A/cm2, beam parameters suitable for pumping excimer laser systems. For this application the gun has the advantages that the -beam is nearly monoenergetic and the pulse widths longer than that possible with other presently used -guns.
