Paper Abstract

Super-Reltron high power microwave tubes use post-acceleration of a well-modulated beam and multiple cavity output sections to generate high power microwave pulses (100MW-1GW) with excellent efficiency (40-50%). In the past year we have continued our development of these tubes with emphasis being given to three specific topics: 1) long pulse operation. Recent experiments with our 1.3-GHz tube have demonstrated pulse durations in excess of one microsecond, producing energy per pulse in excess of 150 J. 2) Extended frequency coverage. We have developed a Super-Reltron-based HPM effects testing system which provides repetitive, high-power pulses over the frequency range of 0.7-11 GHz. 3) Extended lifetime designs. We have now developed Super-Reltron designs using thermionic cathodes, ceramic insulators, and gridless modulating cavities. These designs should give extended lifetime operation at reasonably high average power levels (> 100 kW). In this paper we report our experimental results and theoretical design considerations related to each of these three topics.
