摘要

采用电路模拟得到的柱孔结构处向外磁绝缘传输线传输的电压反射波来等效Z箍缩装置中的柱孔结构至丝阵负载部分,实现了Z箍缩装置四层外磁绝缘传输线的全尺寸粒子模拟.为了进一步提高柱孔结构和丝阵负载等效电路模型的精度,通过粒子模拟,对电路模拟得到的电压反射波进行了修正.PBFA Z装置四层外磁绝缘传输线部分的全尺寸粒子模拟结果表明,修正电压反射波后得到的绝缘堆处电压波形和电流波形比原有电路模拟结果更接近实验结果.另外,利用粒子模拟结果分析和解释了丝阵负载内爆对外磁绝缘传输线脉冲功率传输物理过程的影响.

Abstract

In order to implement the particle-in-cell(PIC) simulation of four outer magnetically insulated transmission lines(MITL) of Z-pinch accelerator, we adopt the backward-going transmission line voltage wave at the double post-hole convolute(DHPC) travelling in the outer MITL direction, which is gained in circuit simulation to model the part from DHPC to Z-pinch load. For the purpose of enhancing the accuracy of equivalent circuit model of DHPC and Z-pinch load, the backward-going transmission line voltage wave that is computed by circuit simulation is rescaled by PIC simulation. The insulator voltage and current waves that are obtained in the PIC simulation of four outer MITLs of PBFA Z can match the electrical measurements better than those obtained by the circuit simulation. Moreover, the influence of Z-pinch load implosion on the process of pulsed power coupling in the outer MILT is analyzed and explained.
