| 摘 要： | Mini-LIA为MHz重复频率双脉冲电子直线感应加速器，由双脉冲功率系统、热阴极电子枪注入器及金属玻璃磁芯感应加速腔等组成。在此平台的实验获得了数百ns间隔（即MHz重复频率）的双脉冲高压，每个脉冲幅值达到80 kV，脉冲半高全宽为80 ns；在感应腔加速间隙处测得双脉冲加速电场；在加速器出口处测量得到流强约1.1 A的双脉冲电子束流。实验结果表明：利用硅堆隔离汇流装置可实现MHz重复频率的双脉冲高压，金属玻璃磁芯感应加速腔和六硼化镧热阴极电子枪均适合MHz重复频率双脉冲工作方式。

| Abstract: | The Mini-LIA is a double-pulse linear induction electron accelerator with megahertz repetition rates, which consists of a double-pulse power system, a thermal cathode electron gun, two induction cells, beam transportation systems and diagnosis systems, etc. Experiments of the Mini-LIA have been conducted. The double-pulse high voltage was obtained with several hundred nanosecond pulse intervals (i.e. megahertz repetition rate) and each pulse had an 80 kV amplitude with a FWHM of 80 ns. In the gap of the induction cell, the double-pulse accelerating electric field was measured via E-field probes, and the double-pulse electron beam with a current about 1.1 A has been obtained at the Mini-LIA exit. These experimental results show that the double-pulse high voltage with megahertz repetition ra |
