同轴型脉冲触发多通道输出气体开关

一种同轴型脉冲触发多通道输出气体开关，本发明的特点是开关的金属外壳呈圆筒状，内部用绝缘材料构建同心轴对称型气室，气室采用径向密封的方式，气室表面呈凹凸状，是为了延长电极之间的滑闪距离，在气室顶部设有充放气两个通道与外部连通，电极按同心轴分层设置，在半球头棒状高压电极上部的外侧固定设置触发电极于气室顶部，再外侧的中空盘状地电极与金属外壳连接，所述的高压电极与触发电极的间距是高压电极与地电极间距的1/3～2/3。本发明具有以下特点，可以同时输出多路(30路)脉冲前沿小于20ns、抖动为2ns的快脉冲信号，使加速器触发系统能够稳定提供120路同步脉冲信号，提高“强光一号”加速器的运行效率。

Coaxial-typepulse trigger multi-channel output gas switch

Acoaxial-type pulse trigger multi-channel output gas switch is characterized inthat a metal shell of the switch is in a cylindrical shape, a concentric shaftsymmetric type gas chamber is constructed in the switch by an insulationmaterial, the gas chamber adopts a radial sealing method, the surface of the gaschamber is in a concave and convex shape in order to extend the slidingdistance between electrodes. The top of the gas chamber is provided with an inflatingchannel and a deflating channel which communicate with the exterior. The electrodesare arranged in a concentric shaft layering mode. The trigger electrode isfixedly arranged at the position, on the outer side of the upper part of a hemispherichead rod-shaped high-voltage electrode, of the top of the gas chamber. A hollowdiscal ground electrode on the outer side is connected with the metal shell.The space between the high-voltage electrode and the trigger electrode is onethird-two thirds of the space between the high-voltage electrode andthegroundelectrode. The coaxial-type pulse trigger multi-channel output gas switch hasthe following characteristics that multiple channels (30-channel) of fast pulsesignals with the pulse front edge being less than 20 ns and jitter being 2 nscan be simultaneously output, an accelerator trigger system can stably providea 120 channels of synchronous pulse signals, and the operation efficiency of a ‘QiangGuang-1’accelerator is improved.
