In this article, a GW-level and high-efficiency S-band eight-cavity relativistic magnetron with diffraction output (MDO) is proposed. A rectangular profile vane-type anode block is adopted to increase the volume of resonators, which leads to a promising higher output power. In particle-in-cell (PIC) simulations, the proposed eight-cavity MDO generates 2.5 GW output power with a power conversion efficiency of 70% when the applied voltage is 460 kV and the axial magnetic field is 0.44 T. The operation mode, π-mode, oscillates at 2.75 GHz. The proposed eight-cavity MDO generates an RF output power over 2 GW in a wide range of voltages and magnetic fields, which exhibits its reliable performance in π-mode.

具有衍射输出的矩形叶片型相对论磁控管


本文提出了一种具有衍射输出（MDO）的GW级高效S波段八腔相对论磁控管。采用矩形叶片式阳极块来增加谐振器的体积，从而有望获得更高的输出功率。在颗粒细胞（PIC）模拟中，当施加电压为460 kV、轴向磁场为0.44 T时，所提出的八腔MDO可产生2.5 GW输出功率，功率转换效率为70%。 π 模式，振荡频率为 2.75 GHz。所提出的八腔MDO在较宽的电压和磁场范围内产生超过2GW的射频输出功率，在π模式下表现出可靠的性能。
