A Compact 36 kJ Electron Beam System for Laser Pumping
Abstract
An electron beam machine consisting of six modules is being constructed for the 'B' amplifier of the RAPIER KrF laser system. Each module consists of a diode, a 5 omega positive charged water dielectric Blumlein pulse-forming line, and a five stage Marx generator. Separate 25 cm x 41 cm electron beams are formed in magnetically isolated diodes which when arranged in groups of three produce two nearly continuous 25 cm x 125 cm beams that enter the laser cell from opposite sides. The pulse-forming lines operate at 450 keV and produce 150 ns long pulses. The lines employ electrically triggered annular SF6 output switches. The two concentric transmission lines of each pulse-forming line are charged in 1 micro s through symmetric circuits to reduce diode prepulse voltage. The six modules together with the laser cell will occupy less than 15m2 of floor space.
