磁绝缘传输线等效电路模型空间电荷流 Magnetically insulated transmission line Equivalent-circuit model Space-charge-limited flow

摘要

根据磁绝缘特征将PBFA Z加速器的4层圆盘锥形磁绝缘传输线结构分成几段串联的集中电感,结合磁绝缘临界电流、空间电荷限制流、Mendd磁压力平衡及丝阵内爆动力学等计算模型,并引入主要的结构参数,建立4层圆盘锥形磁绝缘传输线的等效电路模型,模型计算结果与实验结果、其它模型计算结果符合较好,模型可以用于定性或半定量设计及分析类似结构的磁绝缘传输线.

Abstract

The paper has established an equivalent-circuit model of the four-level-coaxial-circular-cone-like magnetically insulated transmission line of PBFA Z by treating its vacuum section as several pieces of lumped inductance in terms of its magnetic insulation properties. The model has incorporated magnetic insulation theory, space-charge-limited flow theory, Mendel's MITL pressure balance equation, and wire-array implosion dynamic model as well as several critical geometric parameters of the MITL. The comparison of calculated results of a typical PBFA Z test by the model with those by other models and measured results indicates that the model be valid and can be used as a convenient tool to design and estimate similar MITL configurations.
