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