报道了一种能够产生皮秒上升时间多兆瓦脉冲的开关技术的实验方案。目标是确定和展示一种可以扩展到数百千伏并以千赫重复率运行的技术。还需要一个皮秒上升时间、长寿命的开关。研究了能够扩展到更高重复率和能量切换机制的火花间隙技术，特别是流动油间隙开关。在130 kV下的两到三个脉冲击穿试验用于测量高达200 pps的大面积油开关的恢复特性。开发了一种基于流油开关的高重复频率调制器，其脉冲持续时间为数十纳秒。调制器包含三个油开关：（1）转换开关，（2）输出开关和（3）锐化开关。调制器的设计和性能的报告。阐述了电极流动几何形状对油开关恢复的影响，以及油开关沿着的击穿等特性。>
An experimental program undertaken to demonstrate a switch technology capable of generating picosecond-risetime, multimegawatt pulses is reported. The goal was to identify and demonstrate a technology which could be scaled to hundreds of kilovolts as well as operate at kilohertz repetition rates. A picosecond-risetime, long-lifetime switch was also required. Spark gap technology capable of being scaled to much higher repetition rates and energy switching regimes, in particular, a flowing oil gap switch, was investigated. A two to three-pulse breakdown test at 130 kV was used to measure the recovery characteristics of a large-area oil switch at up to 200 pps. A high-repetition-rate modulator based on flowed oil switches that develop pulses tens of nanoseconds in duration was developed. The modulator incorporates three oil switches: (1) a transfer switch, (2) an output switch, and (3) a sharpening switch. The modulator design and performance are reported. The influence of electrode flow geometry on the recovery of oil switches along with their breakdown and other characteristics is described. >
