摘要
设计了一套具有低输出抖动的小型Marx型触发源系统。将充电、触发电源等进行了整体集成,结合高储能密度的四端型薄膜电容器设计,实现了系统的紧凑化,体积仅0.20 m3。将场畸变气体开关电极设计为环形轨道状,采用平面触发方式,以利于开关的低抖动输出和稳定工作。该系统输出电压、工作频率分别在10~90 k V,1~30 Hz范围内独立可调。以30 Hz重复频率工作300次,输出抖动的最大偏差(极差)仅为13.0 ns。相比30 Hz、30次结果,工作时间延长了9倍,输出抖动极差仅增加了38%,表现出极低的输出抖动和高的稳定性,是一种理想的高压触发源系统。
A compact trigger source with low output jitter is designed based on Marx-circuit.The volume of the system is reduced to0.20m3by integration of the charging power supply and triggering power supply,as well as the introduction of a four-terminal film capacitor with high energy density.The annular orbit-shaped electrode and the planar-triggering designs are employed to lower the output jitter and improve working stability of the field distortion spark-gap switch.The impulse voltage and working frequency can be adjusted in the range of10-90kV and1-30Hz,respectively.The maximum deviation ofthe output jitter is as low as13.0ns when the system runs300times at30Hz,which means there is only a38%of growth for the output jitter when the working time increases by nine times.The trigger source is an ideal high-voltage trigger system,which shows low output jitter and high reliability.
