摘　　要：探索了采用CST软件和PSpice软件进行加速器场分布数值模拟的方法,利用该方法可方便地获取设备内部动态场分布图及动态电压变化规律。针对螺旋线型μs级高压长脉冲产生器系统建立了数值模拟模型,给出了详细的模拟步骤及结果。分析表明,利用场分布模拟方法获取的电压变化规律与电路模拟方法获取的结果是一致的。基于CST模拟方法,可以给出螺旋线及主开关等电气结构的瞬态电场分布,场强增强点主要出现在螺旋带的外沿及金属电极连接处,在介质支撑内部也有较高的场强分布。A method to analyze electric field distribution of the accelerator based on CST and PSpice software is introduc（d and the dynamic three dimensional electric field distribution and voltage of the device are obtained. The models for numerical sinm lation of the spiral pulse generator are set up, and detailed results are presented. The changing rules of vohagc oblaincd hy CST are similar to that by PSpice software. The numerical simulation results indicate that higher electric fields appear al the seams and the joint surface of the soiral bands, and the interior of the dielectric strut.
