摘要
在SPARK-04强流相对论电子束加速器上,对轴向反馈式虚阴极振荡器进行了实验研究,并采用远场测量方法对其激励的高功率微波辐射进行了测量,测得了微波辐射主模及辐射功率。结果表明:微波辐射主模为TM01模,辐射功率大于500 MW,微波转换效率大于3%,辐射频率约3.6 GHz,微波脉宽大于20 ns。同时,采用单反射面Vlasov天线,实现了该器件所激励高功率微波的定向传输。
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.
