| 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 kV,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。

| Abstract: | A compact trigger source with low output jitter is designed based on Marx-circuit. The volume of the system is reduced to 0.20 m3 by 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 of 10-90 kV and 1-30 Hz, respectively. The maximum deviation of the output jitter is as low as 13.0 ns when the system runs 300 times at 30 Hz, which means there is only a 38% 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. |
