正在研制的Z箍缩实验装置(Z-pinchPrimaryTestStand,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0.2Ω的低阻抗负载上得到8MA以上电流,电流上升时间小于90ns。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450kA、输出电压2.2MV、输出脉冲功率0.95TW,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6ns。
The Z-pinch Primary Test Set (PTS) under development consists of 24 modules based on the performance and structure of the Marx generator and the waterline. The high-current pulses generated by each module are collected on the insulation stack Magnetically insulated transmission lines converge to the load zone, requiring more than 8MA at a low impedance load of less than 0.2Ω with a current rise time of less than 90ns. The prototype module developed by the Marx generator, the middle of the energy storage device, the laser trigger switch, pulse forming line, self-breakdown of water medium pulse formation switch, three plate type pulse transmission line, the prototype module output current 450kA, the output voltage of 2.2MV, the output pulse Power 0.95TW, the system delay time jitter is less than 6ns from triggering the laser signal output to increasing the load voltage.
