摘要
本文研究了一种全腔提取结构透明阴极相对论磁控管,提取结构采用径向耦合孔与扇形波导耦合输出,结构更加紧凑。我们用三维全电磁PIC程序进行了数值计算,在1.38GHz,我们获得了近3GW的功率输出,效率超过了50%。
A all cavity relativistic magnetron with transparent cathode has been proposed. In this configuration the microwave output is significantly improved. Three_dimensional particle-in-cell simulation was carried out to demonstrate the effectiveness of the modified configuration. In the simulation results the microwave efficiency of 54% has been obtained.
