The present research focuses on the characteristics of a two-stage pseudo-spark switch (PSS). In this project, the pseudo-spark chamber contains three identical electrodes constructed from a stainless-steel material isolated by a glazed ceramic material used as an insulator, with 0.07 m in diameter and 0.003 m in thickness. A pseudo-spark switch of ~ 30 kV anode voltages, 24 kA with 5 ns current rise time and a repetition rate of 160 kHz has been constructed and used effectively. A trigger circuit is designed, constructed and successfully used in a multi-shot mode with high repetition rate; this operation produces a 2.1-kV, 2-μs trigger pulse in width, which is sufficient to provoke and breakdown the argon gas within the cathode. Such a switch has jitter time between pulses less than 8 ns and 8 × 10¹¹A/s rise time rate at a working argon gas pressure 0.3 mbar. The intermediate electrode gives us a high-power switch, which has many applications in medical techniques and in discharge heated copper vapor laser applications. The PSS system lifetime is reliant on the electrodes material type and on insulator material used in the main gap of the PSS.

目前的研究重点是两级伪火花开关（PSS）的特性。在这个项目中，伪火花室包含三个相同的电极，由不锈钢材料构成，由用作绝缘体的釉面陶瓷材料隔离，直径为 0.07 m，厚度为 0.003 m。已构建并有效使用了~30 kV 阳极电压、24 kA、5 ns 电流上升时间和 160 kHz 重复率的伪火花开关。设计、构建并成功应用于高重复率多发模式的触发电路；该操作产生一个 2.1-kV、2-μs 宽度的触发脉冲，足以激发和击穿阴极内的氩气。这种开关的脉冲之间的抖动时间小于 8 ns 和 8 × 10 ¹¹工作氩气压力为 0.3 毫巴时的 A/s 上升时间速率。中间电极为我们提供了一个高功率开关，它在医疗技术和放电加热铜蒸汽激光应用中有许多应用。PSS 系统寿命取决于电极材料类型和 PSS 主间隙中使用的绝缘体材料。
