摘　　要：Z箍缩实验滞止后期负载产生的微小碎片及其他飞溅物质会污染Z箍缩诊断系统内的光学器件,本文研制了一种基于电磁感应原理的快阀,其可用于遮断微小碎片及其他飞溅物质。根据能量守恒和电路方程,计算了快阀的运动速度、遮断时间及线圈放电电流等参数,并利用实验测量获得快阀运动速度为19m/s,遮断时刻时间抖动为85μs,实验测量与计算结果较为吻合。The debris or splashing mass will be produced by Z-pinch loads after the stagnation phase in Z-pinch experiments.The debris can arrive at the diagnosis devices and cause pollution to the optic units.In this paper,a kind of fast shutter based on the principle of electromagnetic induction was developed.The velocity,the discharge current and the shut-down time of fast shutter were analyzed based on the energy conservation principle and circuit model.The experimental results show that the velocity of fast shutter is nearly 19m/s and the jitter of shut-down time is 85μs.These experimental data show a good agreement with the calculation results.
