Abstract

Abstract

In this paper, a relativistic high power microwave generator with coaxial slow wave structure was experimentally researched. The experimental system was set up based on the structure optimized by numerical simulation. Preliminary results show that the generator has the advantage of high beam-wave conversion efficiency. Although the experimental system was not yet in a state of optimization, a microwave pulse with peak power of 1.3 GW and efficiency of 28% was generated. The microwave frequency is about 7.7 GHz and varies very slowly with diode voltage, which is consistent with the results of numerical simulation.
