“阳”加速器丝阵负载内爆数值模拟

Numerical simulation of wire array load implosion on Yang accelerator

基于描述Saturn装置的ZORK模型,使用Pspice语言建立了适用于"阳"加速器计算使用的金属丝阵负载模型并进行了相关计算,经过数值模拟与"阳"加速器1050#,1043#等相关实验结果的对比,验证了驱动电路与相关模型设计的正确性,并对计算结果进行了讨论,给出了此负载模型的适用性分析。使用计算得到的阳1050#加载电流曲线,进行了1维磁流体力学计算,给出内爆时间、辐射功率峰等相关参数。

Based on the ZORK model describing the Saturn facility,a zero dimensional load model of the wire array Z-pinch on Yang accelerator is designed using Pspice to simulate the implosion process.Comparisons between the calculated results and experimental data prove the load model to be correct.The applicability and shortcomings of the load model are presented.One-dimensional magnetohydrodynamic calculations are performed by using the current curve obtained from calculated results of experiment Yang 1050#,and the parameters such as implosion time and radiation X-ray power are obtained.
