中文摘要：
快前沿直线型变压器驱动源（FLTD）是一种可以直接获得100ns脉宽的脉冲功率源新技术，在Z箍缩、闪光照相、强激光和高功率微波方面具有重要应用。为了寻求用于FLTD的多间隙气体开关的合适结构，设计了一种场畸变多间隙气体开关。该开关含有6个间隙，各个间隙距离相等，开关问隙总长度为30mm。开关中间电极为锚式固定结构，每个电极由3只螺钉固定在绝缘筒壁内侧，数值计算了开关的电场分布，实验研究了开关的自击穿及触发特性。结果表明，开关自击穿特性曲线与经验公式曲线基本符合，自击穿电压的分散性〈3．2％；在工作系数为50％时，开关仍能正常触发，触发时延约百ns；在工作系数为60％时，触发脉冲为159kV／15ns的情况下，开关触发时延约60ns，抖动时间约5ns。
英文摘要：
Fast linear transformer driver （FLTD） is a novel high pulsed power source that can directly drive fast Zpinch load, radiography, high power laser and high power microwave etc. Switch is one of the most important components which affects the characteristic of LTD module. A new multigap gas switch has been developed, which is composed of six equal gaps in series. The total gap distance is 30 mm. In the switch, every intermediate electrode is anchored to the insulated casing by three bolts. The electric field distribution of the switch has been analyzed for designing switch. Experimental results show that the curve of the switch self-breakdown voltage is conformable to the empirical formula ,and the divergence of the switch self-breakdown voltage is less than 3.2 %. When the ratio charging voltage to self-breakdown voltage is 50%, the switch can be triggered easily and the delay time is about 100 ns. When the ratio charging voltage to self-breakdown voltage reaches 60% and the trigger pulse is 150 kV/15 ns, the delay time reduces to 60 ns, and the jitter time is less than 5 ns.
