Status of repetitive pulsed power at Sandia National Laboratories

Multi-kilojoule repetitive pulsed power technology moved from a laboratory environment into its first commercial application in 1997 as a driver for ion beam surface treatment. Sandia's RHEPP II (Repetitive High energy Pulsed Power), a repetitive 2.5 kJ/pulse electron beam accelerator, has supported the development of radiation treatment processes for polymers and elastomers, food products, and high dose-rate effects testing for defense programs since early 1996. Dos Lineas, an all solid-state testbed, has demonstrated synchronization techniques for parallel magnetic modulator systems and is continuing the development of design standards for long lifetime magnetic switches and voltage adders at a shot rate capability that exceeds 5/spl times/10/sup 6/ pulses per day. This paper describes progress in multi-kilojoule class repetitive pulsed power technology development, magnetic switching technology for modulator applications, and future research and development directions.
