Accurate control technology of 24 modules in PTS

  • 摘要: 介绍了Z箍缩初级实验平台“聚龙一号”装置24路模块的精确控制技术和实验结果, 通过采用24个激光触发开关来控制24路模块的精确导通, 实现了对“聚龙一号”装置输出电流波形的精确控制和调节。24个激光触发开关由12台Nd: YAG四倍频脉冲激光器来触发, 每台激光器分光后触发2路激光开关。实验结果表明: 24路激光之间的抖动小于1.0 ns, 激光开关的抖动小于1.5 ns,“聚龙一号”装置在主Marx充电电压为65 kV时, 当24路模块同步导通时,获得负载电流9.8 MA, 电流前沿上升时间(10%~90%)为75 ns;在24路模块分时放电时,实现了对电流波形的精确调节,电流前沿上升时间(10%~90%)可以拓展到600 ns, 对应的负载电流峰值为5.5 MA,电流波形的模拟值与实验测量结果基本一致,在相同负载和实验条件下,获得的电流波形具有很好的重复性。
