Development of driving power supply for short pulse high yield neutron generator

  • 摘要: 真空弧中子发生器是一种短脉冲高产额的中子源,被广泛应用在石油测井、元素活化分析等领域。真空弧中子发生器的典型特点是放电弧流大、脉宽短,为此研制了一套大电流的真空弧放电及其引出电源,包含触发模块、主弧模块和引出模块等。触发模块为LRC放电,输出电压峰值大于5 kV。主弧模块采用LRCD半周期放电方式产生主弧电流,电流峰值大于600 A,半高宽大于0.5 μs。引出模块使用多倍压整流电路,将交流高压整流成所需的高压直流,输出电压峰值大于120 kV,负载电流大于2 A。根据设计方案建立了仿真模型,仿真结果表明该电源能很好地输出设定的电参数。最后制备了一套大电流真空弧放电及引出电源,测试结果表明该电源输出参数和设计值一致,可用来作为真空弧中子发生器驱动电源。
