摘要: 对“强光一号”加速器预脉冲气体开关特性进行了初步研究,估算开关固有电容等电气参数,给出了开关的直流自击穿特性。在此基础上,针对“强光一号”加速器预脉冲的特点,选取加速器中的预脉冲开关的工作间距及工作气压,在开关间距为24mm,气压为6.0×105Pa时,成功的抑制了预脉冲。Abstract: The gas switch is one of the commonly employed parts in accelerators. The pre-pulse gas switches in Qiangguang-I is studied in this paper. The parameters of the gas switches are calculated, and the characteristics of switches under constant voltage are obtained through calculation and experiments, on the basis of which the switch gap and pressure are determined to eliminate the pre-pulse voltage to the diode. Both the simulation waveforms and experimental waveforms are shown finally.
