摘要: 简要阐述了脉冲变压器型重复脉冲强流电子束加速器CHP01的组成、主要特点及工作原理，利用设计的重复脉冲强流电子束源进行了长时间运行实验研究，实验结果达到：在100 Hz重复频率下连续运行5 s，脉冲变压器能稳定输出电压1.15 MV,强流束二极管输出电压超过800 kV、束流7 kA、脉冲宽度45 ns，阴极电子发射密度超过10 kA/cm2，且运行稳定可靠。利用该电子束源进行了X波段类周期慢波结构微波器件实验研究，在50 Hz重复频率下连续运行5 s，输出微波功率超过1 GW，脉冲宽度大于25 ns。Abstract: The components, main characters and operation principles of the repetitive pulsed and intense current electron- beam accelerator which is based on pulsed transformer are introduced in this paper, on this equipment, the experiment study of long- time and stable operation of electron- beam source are carried out, and the results reach or partially exceed the designed parameters. While the repetition rate is 100 Hz, the pulsed transformer can deliver high voltage pulse of 1.15 MV, the intense current electron- beam diode can operate steadily as long as 5 s, its output beam voltage exceeds 800 kV, beam current exceeds 7 kA, pulse width is 45 ns, and the emission density of cathode is near 10 kA/cm2. A quasi- periodic slow wave structure device is studied using this electron- beam source, the r
