Abstract

In a numerical experiment based on nonstationary codes, it is shown that introduction of reflections at the ends of the slowing structure of a relativistic backward wave oscillator operating in the superradiance mode provides conditions for the formation of a sequence of powerful ultrashort microwave pulses during a single current pulse. The pulse repetition frequency is specified by the time of propagation over the feedback circuit and can amount to ∼100 MHz. The conversion factor defined as the ratio of the peak power of the ultrashort pulse to the electron beam power is about 3 for the first (main) pulse and decreases to ∼2 for subsequent pulses.

基于相互作用空间末端带有反射镜的相对论后波振荡器的超辐射效应，产生一系列强大的超短微波脉冲

摘要

在基于非平稳代码的数值实验中，表明在超辐射模式下运行的相对论后向波振荡器的减慢结构的末端引入反射，为在单个脉冲期间形成一系列强大的超短微波脉冲提供了条件。当前脉冲。脉冲重复频率由反馈电路上的传播时间指定，总计约为100 MHz。转换因子定义为第一个（主）脉冲的超短脉冲峰值功率与电子束功率之比约为3，随后的脉冲则降至约2。
