Abstract

In this paper, we numerically analyze a “capillary” type plasma source used to create plasma liners in gas puff z-pinch experiments. It is shown that erosion from a plasma source of this type, observed in the experiment, is provided by evaporation of the electrodes. Moreover, the main contribution comes from evaporation from the anode. The calculation results are in qualitative agreement with the experimental data.

大电流等离子体源的数值模型
本文用数值方法分析了一种“毛细管”型等离子体源在气体吹胀z夹缩实验中产生等离子体衬里的方法。结果表明,在实验中观察到的这种等离子体源的侵蚀是由电极的蒸发提供的。此外,主要贡献来自阳极的蒸发。计算结果与实验数据定性一致。
