摘要: 介绍在L波段强流相对论速调管研究中,强流相对论短脉冲空心电子束的产生、传输、束流调制及其诊断等方面的初步实验研究情况。在直线感应加速器上,利用66mm、壁厚3mm的石墨空心阴极,加上约5kGs的准直流引导磁场,引出了约500kV、4.5kA、脉宽100ns、54.5mm、厚度4.5mm的空心电子束。注入500kW的微波调制,束流经过输入腔后,得到了约6%的最大基波电流调制深度,经过中间腔后,得到了约23%的基波电流调制深度。Abstract: Emission, translation, modulation and diagnosis of short pulse intense relativistic hollow electron beams (IREBs) of a L-band relativistic klystron amplifier are described in this paper. The hollow electron beams about 500kV, 4.5kA, diameter 54.5mm, thickness 4.5mm are obtained, and 6% of beam current modulation is gotten after the electron beams get through the input cavity gap, as well as 23% of beam current modulation is gotten after the electron beams get through the idler cavity gap.
