正在研制的Z箍缩实验装置(Z-pinch Primary Test Stand,PTS装置),由24个基于Marx发生器和水线的性能、结构相同的模块组成,各模块产生的大电流脉冲在绝缘堆上汇集后经磁绝缘传输线汇流到负载区,要求在不到0.2 Ω的低阻抗负载上得到8 MA以上电流,电流上升时间小于90 ns。研制的样机模块由Marx发生器、中间储能器、激光触发开关、脉冲形成线、水介质自击穿脉冲形成开关、三板型脉冲传输线组成,样机模块输出电流450 kA、输出电压2.2 MV、输出脉冲功率0.95 TW,从触发激光器信号输出到负载电压上升的系统延迟时间抖动小于6 ns。

In order to study the physics of fast Z-pinches and the key issues of pulse power technology,a 10 MA/6 MV Z-pinch Primary Test Stand(PTS) composed of 24 modules will be built in Institute of Fluid Physics.The prototype module adopting capacitive storage scheme has been built and tested.It is composed of a 6 MV/300 kJ Marx generator(MG),intermediate storage capacitor(IC),laser-triggered switch(LTS),pulse forming line(PFL),water self-breakdown switch(WS),and a tri plate pulse transmission line(PTL).The measured output current of the prototype is approximately 450 kA,and the output voltage is approximately 2.2 MV.The unique multi-stage LTS based on uniform field distribution design and multi-pin unsymmetrical WS makes the prototype modules have low systemic delay jitter which is necessary for synchronization of multi-module facility.1-δ jitter of delay of the system is less than 6 ns.
