天光Ⅱ-B强流脉冲电子加速器的设计

Design of Light Ⅱ-B Pulsed Power Electron Accelerator

  • 摘要: 为了驱动X箍缩负载,在天光Ⅱ-A的Marx油箱侧面建立了一条新的实验线路天光Ⅱ-B。它在保留装置原有泵浦激光能力的基础上,还可进行X-pinch相关实验研究,达到了一器两用的目的。天光 Ⅱ-B主要由Marx发生器、脉冲形成线、主开关、脉冲传输线和负载构成,形成线工作介质为去离子水,形成线特征阻抗6 Ω,传输线采用变阻抗线设计,负载特征阻抗1.25 Ω。本文介绍了天光Ⅱ-B新线的设计、全电路模拟及在电阻负载下的调试结果。模拟和调试结果显示,天光Ⅱ-B装置在负载电阻为1.25 Ω时,负载上的电流峰值约269 kA,脉宽约50 ns,电流上升时间小于30 ns。以上结果证实,天光Ⅱ-B具有驱动低阻抗X-pinch实验线路的能力。

     

    Abstract: The Light Ⅱ-B was built at the side of the Marx tank of Light Ⅱ-A for X-pinch test, which kept the original capacity of KrF excimer laser, and can be used for relevant researches of X-pinch. It is composed of a Marx generator, a pulse forming line (PFL), a gas-filled switch, a pulse transmission line (PTL), and a copper-sulphate resistive load. The medium of the forming line is deionized water. The input impendence of the pulse forming line is 6 Ω, corresponding to an output impendence of 1.25 Ω for the pulse transfer line. The design of circuit simulation and the debugging results in resistance load were introduced. The results show that the current peak load is about 269 kA, pulse width is about 50 ns, and the current rise time is less than 30 ns when the load is 1.25 Ω. It indicates that Light Ⅱ-B has the ability to drive low impedance X-pinch experimental line.
