摘要

摘要: 详细介绍了基于形成线并联和传输线延时两种不同技术路线的MHz重复率猝发多脉冲加速组元的工作原理、应用背景和技术特点，针对现有传输线延时双脉冲加速组元的主要问题提出了一种新的猝发高压双脉冲加速组元设计思路并进行了实验验证，使双脉冲加速组元在兼顾更高稳定性和更好波形品质的同时，解决了双脉冲电压独立调节、间隔调节及单双脉冲模式转换的问题。

Abstract: As the light source to provide multi-time radiography, multi-pulse linear induction accelerator (LIA) needs each of its accelerating module to produce several induction pulses in ~μs, with ~100 ns pulse width and ~200 kV pulse voltage. Two kinds of multi-pulse accelerating modules are introduced and compared in this paper, one is based on pulse forming line (PFL) parallel connection method, the other is based on pulse transmission line (PTL) time-delay method. A new design of double-pulse acceleration module is advanced, and the principle experiments' results are discussed.
