Summary form only given. We have investigated an efficiency enhancement of high power microwave generation from axial virtual cathode oscillator by adopting a bar type reflector in this experiment. This high power microwave generator is powered by the "Chundoong" intense relativistic electron beam pulser (Max : 600 kV, 88 kA and 60 ns duration). It is noted in this experiment that the maximum power can be obtained at A-K gap distance of 4 mm. Experiment shown that output microwave main frequency is 4.72 GHz from axial vircator without a bar reflector. It is found in this experiment that the output microwave power sensitively depends upon the position of a bar reflector. The microwave peak power with a bar reflector has been measured to be about 200 MW which is almost two times enhanced by bar reflector in comparison with that without bar reflector. |
