摘　　要：　以预 主脉冲方式工作的激励软X光激光毛细管放电装置,其预 主脉冲先后触发时间间隔的控制,直接影响了泵浦能量转换为X射线激光能量的效率。运用光电耦合及脉冲变压器隔离等技术,将集成芯片构成的延时电路用于快速高压放电装置中。实验结果表明,预 主脉冲协调工作,延时触发2～50μs,为产生软X光激光提供了条件。When the capillary discharge device runs with pre-pulse and main-pulse, its efficiency of energy transferring by bumping to X-ray laser rises. The control of trigger delay time from pre-pulse to main-pulse is very important for this device. Based on the introduction of the circuit to generate pre-pulse, the delay circuit which consists of IC chip is applied in the high-voltage fast discharge system by the technology of photoelectric coupling and pulse transformer isolation, the delay time can be adjusted continuously, and the experimental results about the adjustment of pulses are given, the results prove that the delay time of the circuit is from 2 μs to 50 μs and it is good for producing soft X-ray laser.
