有限温度、限制在磁性表面上的低密度纯电子等离子体平衡方程的二维解 [T. S. Pedersen 和 A. H. Boozer，物理学家。莱特牧师。 88, 205002 (2002)]首次提出。与潘宁陷阱平衡相反，这些平衡不是最大能量状态 [J.诺特等人，物理学。莱特牧师。 69, 3056 (1992)]。通过改变等离子体中德拜长度的数量，a/λD，从 0.1 到 10，我们探索相对温暖和相对冷的等离子体平衡。讨论了不同边界条件的影响以及对碰撞传输率的影响。
Two-dimensional solutions to the equilibrium equation for finite temperature, low density pure electron plasmas confined on magnetic surfaces [T. S. Pedersen and A. H. Boozer, Phys. Rev. Lett. 88, 205002 (2002)] are presented for the first time. These equilibria are not maximum energy states, in contrast to Penning trap equilibria [J. Notte et al., Phys. Rev. Lett. 69, 3056 (1992)]. By varying the number of Debye lengths in the plasma, a/λD, from 0.1 to 10, we explore both relatively warm and relatively cold plasma equilibria. The effects of different boundary conditions and the implications for collisional transport rates are discussed.
