Super-Reltron progress

Abstract

We have continued to develop our high-efficiency, high-power Super-Reltron microwave tubes. We have now achieved 600 MW and >200 J/pulse with our 1 GHz tube, and >350 MW at nearly 50% power efficiency with our 3 GHz tube. We have also developed a tunable version of our 3 GHz tube which has a 3 dB tuning range of /spl plusmn/5% about the center frequency. We discuss these experimental results in this paper, and present a modified performance chart which facilitates tube design for various applications.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
