论文摘要
已经提出了一个模型，用于估计真空排放中爆炸性电子发射脉冲的等离子体参数。它基于爆炸过程中通过临界状态的过渡，并允许预测各种材料的阴极斑点等离子体参数。阴极耀斑等离子体离子动能估计约为临界温度的100倍。平均离子电荷估计为（EV中的1 +临界温度值）。两种依赖性都与实验结果一致。每次转移电荷的爆炸性电子发射质量动量已被评估为大约几十g cm /（s c），并且与测得的离子速度和侵蚀速率的乘积一致。已经提出了有效的临界温度方法，以估计表面弧燃烧的血浆特性
A model has been proposed for estimation of plasma parameters of explosive electron emission pulses in vacuum arc discharge. It based on transition through the critical state during the explosion and allow to predict the cathode spot plasma parameters for various materials. The cathode flare plasma ions kinetic energy was estimated to be of about 100 times critical temperature. Average ions charge has been estimated as (1 + critical temperature value in eV). Both dependencies agree with experimental results. Explosive electron emission plasma momentum per transferred charge has been evaluated to be about tens of g cm / (s C) and agrees with the product of measured ions velocity and erosion rate. Effective critical temperature approach has been proposed for the estimation of plasma properties for the arc burning at surface with a fine structure
