摘要

采用点质量计算方法对多台脉冲功率机的开关内爆进行了模拟。该模型包括脉冲电源的集总电路表示。用一个简单的开关模型来描述一个标准的等离子体流量开关。内爆动能的收敛比为20比1。用启发式参数估计了掐点等离子体温度、总x射线输出和辐射脉冲宽度。介绍了飞马2号、湿婆星、Procyon和阿特拉斯的切换模型。

How do plasma flow switches scale with current? Issues in the 6 MA to 30 MA regime
Point mass calculations are used to model switched implosions on several pulsed power machines. The model includes a lumped circuit representation of the pulsed power source. A simple switching model is used to describe a standard plasma flow switch. Implosion kinetic energies are obtained at a convergence ratio of 20 to 1. Heuristic arguments are used to estimate the plasma temperature at pinch, the total X-ray output and the radiation pulse width. Switched models are presented for Pegasus II, Shiva Star, Procyon and Atlas.
