研究了具有静电限制势的磁镜场中粒子端面损耗的基本问题。Pastukhov、Chernin和RosenBluth的分析方法已推广到适用于多组分等离子体中的任何静电受限物种，Pastukhov分析已扩展到适用于任意磁场分布(而不是方势垒)。将解析结果与一维Fokker-Planck码和二维Fokker-Planck码的结果进行了比较。特别考虑了电势、镜面比和有效电荷的定标问题。最接近的一致性(在20%以内)是在2-D福克-普朗克和广义的帕斯图霍夫结果之间。
The basic problem of particle end-loss in a magnetic mirror field with an electrostatic confining potential is considered. The analytic treatments of Pastukhov and Chernin and Rosenbluth have been generalized to apply to any electrostatically confined species in a multi-species plasma, and the Pastukhov analysis has been extended to apply to arbitrary magnetic-field profiles (instead of square-well). The analytic results are compared with results obtained from one-and two-dimensional Fokker-Planck codes. In particular the scaling with potential, mirror ratio, and effective charge is considered. The closest agreement (within 20%) is between the 2-D Fokker-Planck and generalized Pastukhov results.
