摘要

在分析考虑和数值模拟的基础上，本工作证明了阶梯式射频电场分布的透射时间管可以提供超过40%的电子转换效率。这表明，与纵向均匀电场分布相比，转换效率提高了两倍。这种改进是由于沿相互作用空间反向符号的射频电场的作用而产生的相位同步过程。

Electron bunching in stepped electric-field profiles

On the basis of analytical considerations and numerical simulation, this work demonstrates that transit-time tubes with stepped RF electric-field profiles can provide electron conversion efficiency in excess of 40 percent. This represents a two-fold enhancement in the conversion efficiency in comparison with that obtained with a longitudinally uniform electric-field distribution. Such an improvement arises from a phase synchronization process due to the action of RF electric fields of reversed signs along the interaction space.
