| 摘 要： | 设计了一种无外加引导磁场S波段相对论返波振荡器,采用阳极网提取电子,并设计了非均匀慢波结构。通过Karat 2.5维全电磁粒子模拟程序研究了器件内束-波作用的物理过程。典型模拟结果为:当二极管工作电压330 kV、电流2.83 kA时,器件在频率2.79 GHz处获得较高的微波输出,经27 ns后饱和,输出微波的功率达158 MW,效率约为16.8%。

| Abstract: | An S-band relativistic backward wave oscillator without external guiding magnetic field has been investigated using the Karat 2.5D particle-in-cell simulation code.An anode foil is used to extract the electron beam and the non-uniform slow-wave-structure is designed for increasing the microwave output power of the device.Detailed beam-wave interaction pictures in the oscillator were presented.The simulation results show that a 2.79 GHz,158 MW high power microwave can be obtained when the beam energy is 330 ... |
