MV级重复频率三电极气体开关的优化研究

 对一种高工作电压、高重复频率的三电极气体开关的优化设计方法进行了研究，包括绝缘结构的优化、最优触发孔径和触发电极位置的选取。采用设计开关开展了实验研究，并对实验结果进行了分析。结果表明，开关实现了工作电压1.1 MV，峰值电流约13.8 kA，重复频率100 Hz的最大稳定运行参数，性能满足设计要求；开关绝缘恢复性能良好，各次电压波形幅值均匀，分散性小，归一化标准偏差小于3%。

Optimization of MV-class repetitive trigatron switch

Studies were carried out to optimize the operation of a high-voltage and high-repetition-rate trigatron switch,including optimization of the insulation structure,the diameter of the trigger hole and the position of the trigger electrode.Some experiments were performed with the designed switch,and the experimental results were discussed.The experimental results prove that the switch can operate steadily at voltage up to 1.1 MV,peak current up to about 13.8 kA,and repetition rate up to 100 Hz.The switch has been successfully used in a repetitive high-current e-beam accelerator CHP01.
