摘要
为了驱动重复频率运行高阻抗X光管，设计了基于光导开关的级联Blumlein型脉冲形成网络。采用数值模拟方法优化网络参数，从网络充电电压一致性、输出脉冲波形畸变、电压叠加效率、负载预脉冲幅值出发确定了充电电感和支撑电感设计原则。实验表明: 光导开关工作场强23.2 kV/cm，激光触发能量3.5 mJ时，阻抗约15.6 Ω的Blumlein型脉冲形成网络电压转换效率为0.71，2级级联网络电压叠加效率0.96。
Abstract
A stacked Blumlein pulse forming network(B-PFN) was designed to drive repetitive high-Z X-ray diode. Numerical simulation was adopted to optimize the system parameters, through which inductance design principle was aquired. B-PFN performance was analyzed from several aspects: consistency of charging voltage, distortion of output wave, efficiency of stacked voltage and amplitude of load pre-pulse. Experiments showed that the single B-PFN voltage efficiency was 0.71, the two-stage stacked voltage efficiency was 0.96, when PCSS electric field was 23.2 kV/cm and trigger laser energy was 3.5 mJ.
