Abstract:

The thrust of the joint UMDHRL research program was to improve the understanding of physics issues in the operation of the pasotron, and to - exploit this knowledge by improving the tubes performance. This study was extremely successful. The innovation of using a tailored-profile, plasma neutralized electron beam yielded an increase in the total pasotron efficiency 17 to -32, and an electron efficiency of -40. Moreover, our theoretical results indicate that the pasotron efficiency, after optimization, may be as high as 60-70. Both theoretical and experimental results will be described below.
