An alternative way for calculating the magnetic field in the Lee Model Code has been used. The effects of the various anode-tip shapes on the DPF behavior have been studied. The current and impedance calculations have been employed for these investigations. For the conical anode tip, the best pinch current and soft x-ray radiation have been seen in simulations which was in good agreement with the empirical results. The investigations were carried out for the voltages of 11, 12, and 13 kV and the pressure range of 1–6 Torrs. The asymmetry in the discharging current has been investigated through three arbitrarily defined cathode current distribution patterns. The simulations showed that asymmetry in the axial discharge current increased the plasma Impedance and consequently reduced the soft x-ray emission.

阳极头形状对致密等离子体聚焦装置氮软X射线发射的影响：使用修正Lee模型代码的数值研究与实验相结合

在 Lee 模型代码中使用了另一种计算磁场的方法。已经研究了各种阳极尖端形状对 DPF 行为的影响。这些研究采用了电流和阻抗计算。对于锥形阳极尖端，在模拟中看到了最好的夹断电流和软 X 射线辐射，这与经验结果非常吻合。对 11、12 和 13 kV 的电压和 1-6 Torrs 的压力范围进行了研究。通过三种任意定义的阴极电流分布模式研究了放电电流的不对称性。模拟表明，轴向放电电流的不对称性增加了等离子体阻抗，从而减少了软 X 射线发射。
