摘要: Marx发生器建立时间及抖动与Marx发生器中球隙开关的工作状态有关，同时与开关的触发电压幅值及极性有关。通过实验获得了Marx发生器建立时间及抖动最小时最佳工作状态的相关参数。天光一号电子束加速器从同步机发出指令信号至主Marx输出，总的延时及抖动为（1629±8.4）ns，满足MOPA系统建立时间抖动小于20ns的要求。Abstract: Building time and jitter of the Marx generator are mainly depend on work state of spark gap switch during operating. Meanwhile they are related to amplitude and polarity of trigging voltage. The paper briefly describes physical process of conductance of gas spark gap switch. In order to minimize building time and jitter, experiments were performed to optimize work state related parameters of the Marx generator. As result, the total building time and jitter are (1629±8.4)ns for HeavenΙ electron beam accelerator. It fills the jitter requirement of MOPA system less than 20ns．
