摘要
本文叙述了所研制的一台小型高重复频率电子束加速器装置。该装置的设计指标为:输出电子束能量:120—150keV;电子束流强:5—50A;脉宽:1μs;重复频率:100Hz;电子束截面积:5×50cm^2。本加速器的主体是具有独特优点的WIP电子枪。本文着重分析了这种电子枪的工作原理和物理过程,并给出初步实验结果。
The development of a compact high repetition rate electron beam accelerator is reported. The specifications of the device are output electron energy 120-150keV, beam current 5-50A, pulse duration 1 μs, beam cross-section 5 × 50cm2 and repetition frequence lOOHz. The key part of the accelerator is a wire-ion-pla-sma (WIP) electron gun of particular advantage. The principle of operation of the WIP electron gun and its physical properties are described. The caculation formula of output parameter is given and preliminary experimental results are presented.
