Applied Physics Research for Innovation in Pulsed Power

Abstract

The program addressed fundamental issues in pulsed power technology, emphasizing new GaAs based solid state switches, and new high power thyratron type switches. Results included demonstration of a fast GaAs-based vertical FET- type switch for power modulator, radar and microwave applications, and development of super-emissive cathode switches. Transition of this research to technology is discussed first, then summaries of some of the recent activity are presented. Technology transitions from the research include initiation of a small business in the area of pulsed power technology, substantial impact on modern high power thyratron technology, and impact on the development of solid state devices, including GaAs-based structures. Ongoing work that is related to technology transfer includes development of electron beams for fusion (electron beam ion trap), accelerator and microlithography applications, and development of cathodes with ultra-high emission properties (super-emissive cathode).
