几项新技术在“闪光二号”加速器上的应用

 为追踪国际上脉冲功率技术的发展方向，在“闪光二号”加速器上开展了水介质形成线并联技术、多级多通道气体开关技术和同步触发技术等研究。经过3维结构下电场分布的模拟计算和绝缘设计，采用3根6 Ω小水线并联组成了2 Ω水介质形成线,研制成功了作为主开关的3 MV多级多通道气体触发开关，并实现了3个多级多通道气体开关的并联运行;采用工作时延446 ns的同步触发系统实现了Marx发生器与主开关的延时同步运行。真空负压下的涡流循环冲刷消除水中气泡技术应用于水介质形成线上，有效消除了并联形成线汇聚结构处的气泡，提高了加速器运行的安全性。经过调试后，加速器重新获得了稳定的运行状态，几项新技术的应用获得成功。

Application of new techniques to "Flash-Ⅱ" accelerator

For keeping up with the international development of pulsed power technology，some new techniques such as the water coaxial line parallel connection, the multi-gap multi-channel gas output switch and synchronized trigger system have been studied on “Flash-Ⅱ”accelerator. 2 Ω pulse forming line(PFL) formed by three small 6 Ω PFLs with parallel connection after simulating electric field distribution on the three-dimensional and the insulation designing. The 3 MV multi-gap multi-channel gas output switches have been developed and three switches have been synchronously operated with parallel connection. Synchronized trigger system that operation delay is only 446 ns has been applied in synchronous operation between Marx generator and main switches. The water treatment technique in which wh
