摘要
基于硅堆隔离网络的多脉冲直线感应加速器(LIA)需要外接独立的复位系统,以满足其加速腔磁芯在主脉冲励磁前的复位需求。介绍了猝发三脉冲LIA外接复位系统的工作原理、电路参数以及具体的电路设计,并针对大型LIA感应腔数量众多、运行时电磁环境复杂的特点,介绍了复位系统在工程实施中的主要技术难点和最终布局。该复位系统解决了磁芯在励磁和复位这两种高压模式间的切换问题,实现了10~20 kV可调复位电压的稳定输出,建立了在复杂电磁环境下可稳定运行的远程监控系统,确保了三脉冲LIA的92个加速腔能够在主脉冲励磁前稳定、快速、充分的复位。
Abstract
The triple-pulse linear induced accelerator (LIA) based on high voltage rectifier diodes needs an external reset system, for the diodes cut off the prepulse of the PFL charging which is used to reset the cavity cores of the single-pulse LIA. This paper describes the physics and circuit designs of the external reset unit, and introduces the layout of the whole reset system which includes other more units for charging, triggering and control. As a result, the system can reset the whole 92 cavities of the triple-pulse LIA steadily, quickly and fully.
