摘　　要：介绍了多级多通道气体开关的实验研究工作。开关在电脉冲触发（触发脉冲幅值85kV）条件下，工作电压在1．0～2．0MV范围内能够正常工作。自击穿实验验证了Bradley经验公式对于这种开关的适用性，外触发实验研究得到了开关的触发特性。结果表明：开关击穿延时小于100ns，抖动小于8ns；3个开关击穿时刻之间的极差小于10ns。A new multi-stage and multi-channel closing switch （MMCS） was designed for main switch of Flash- Ⅱ accelerator. The synchronization of three MMCS is important in operation, thus the characteristic of MMCS should be consistency. According to Bradley experiential formula, parameter setup of MMCS was acquired from the experiment in low-voltage condition on Flash-Ⅱ. In the condition of trigger pulse voltage 85 kV, closure voltage 1.0-2.0 MV, the working state of MMCS was stable and reliable in operation. At the same time, property data of MMCS were acquired, the delay time of MMCS was less than 100 ns, the jitter was 8 ns, the breakdown time among the three MMCS was less than 10 ns.
