摘　　要：通过理论计算和数值模拟方法研究了"闪光二号"加速器多针水开关放电通道电流均匀性对开关电感的影响,得到了各个放电通道电流分布不均匀对开关电感的影响规律。理论计算和数值模拟结果均表明,随着多针水开关放电通道电流不均匀性的增加,开关电感显著提高。采用保角变换和构造拉格朗日函数的方法证明了当多针水开关所有放电通道电流一致时开关电感最小,得到了"闪光二号"加速器多针水开关电感最小值为27nH,最大值为153nH。The influences of current uniformity of all discharge channels on the inductance of multichannel water switch of Flash-II accelerator have been studied by both theoretical calculation and numerical simulation.The results show that the switch inductance increases significantly with the increase of the current nonuniformity of the discharge channels of the multichannel water switch.Based on the methods of conformal transformation and the Lagrange function,it is proved that the switch inductance is the minimum when the current of all discharge channels of the multichannel water switch is consistent.The maximum and the minimum values of the inductance are 153 nH and 27 nH respectively for the multichannel water switch of Flash-II accelerator.
