Abstract

Abstract

An experiment on an axial feedback vircator was performed on the intense electron beam accelerator SPARK-04. The far-field measurement method was employed to obtain the main mode and the power of the microwave generated by this device. The experimental results showed that the main mode of the radiation was the TM01 mode, and the microwave power exceeded 500 MW, with an power efficiency of above 3%, a radiation frequency of about 3.6 GHz, and a pulse width of over 20 ns. In the experiment, the directed propagation was achieved for the microwave generated by the vircator through the use of a Vlasov antenna with a microwave reflector.
