摘　　要：介绍了100 kA快脉冲直线变压器驱动源原型模块及其采用的200 kV多级多通道气体开关的设计和初步实验结果。该模块由20台100 kV/20 nF电容器按10个支路并联组成,其中每个支路包括2台电容器、1只多级多通道开关以及相应的传输线。模块直径约1.5 m,厚度仅为20 cm。采用B-dot探针诊断负载电流。当充电电压为±90 kV时,在1.1Ω负载上可得到102.2 kA的峰值电流,上升时间为53.6 ns,脉冲宽度为133 ns。实验结果表明,该快脉冲直线变压器驱动源模块具有较好的快脉冲输出能力。This paper describes the design and test results of an liner transformer driver（LTD） stage prototype and its multi-gap switch.This stage consists of 20 storage capacitors（100 kV/20 nF） that are arranged in 10 identical bricks locating evenly around the axis of the stage.Each brick contains two capacitors,a multi-gap switch,and the output connector that transfer the energy to the resistive load.The outer diameter of the stage is about 1.5 m,at a thickness of 20 cm.The load current was measured by B-dot probe.The magnetic core was premagnetized before each shot.At the charge voltage of ±90 kV,the stage can deliver 102.2 kA fast pulse with a FWHM of 133 ns into a 1.1 Ω resistive load.The experimental results show that the LTD stage has the capability of fast pulse output.
