| 摘 要： | 从理论上分析了脉冲形成线中筒与外筒之间的连接电感对二极管输出电压的影响，使用Pspice软件对理论计算结果进行模拟验证，并利用水介质螺旋脉冲形成线型电子束加速器进行了实验研究。理论分析、软件模拟和实验结果均表明:中筒与外筒之间过大的电感可使输出电压脉冲的平顶变短，上升沿时间延长，波形峰值降低。当连接电感小于200 nH时，可在加速器场发射真空二极管上输出接近方波的电压脉冲。

| Abstract: | Based on the experimental device of the water spiral pulse forming line(PFL) type electron beam accelerator, the effect of inductance between the middle and outer cylinders of PFL on diode voltage is theoretically and experimentally studied in this paper. The formulae are introduced, with which the effect of inductance on diode voltage is calculated. In addition, the diode voltage waveform is simulated through the Pspice software. The theoretical and simulated results agree well with the experimental results, which show that large inductance between middle and outer cylinders can shorten the waveform flat part of diode voltage, increase waveform rise time and reduce the diode peak voltage. When the inductance is smaller than 200 nH, a nearly square voltage waveform can be obtained in field |
