Development of a Reliable, Low-Cost, Energy-Storage Capacitor for Laser Pumping

Abstract

The 14.5-µF, 20-kV energy discharge capacitor developed in the 1950’s far exceeds the present needs of laser fusion research. This unit was designed to operate under conditions of large voltage reversal and high peak currents. In glass-laser systems, voltage reversal occurs only during occasional faults, and peak currents are below 1000 A. It is relevant, therefore, to pursue lower-cost, higher energy-density capacitors, which more closely fit the requirements of laser fusion research. Several companies have designed and produced prototype units that meet the cost criteria of 5 to 6¢/J and energy density of 5 to 6 kJ/unit.
