两种类型的等离子体平衡的自洽计算的三电极Malmberg-Penning陷阱，有一个增加的中心电极的一部分的半径。当一个单一的物种，完全非中性的等离子体被限制在陷阱内，平衡的等离子体产生一个三维的电势以及预测。预计通过将符号相反的第二等离子体物质限制在由第一等离子体物质产生的三维井内，部分非中性等离子体平衡是可能的。部分非中性等离子体平衡是自洽可能的必要条件的报告。然后具体考虑由电子和单电荷氙离子形成的部分非中性等离子体，首先将离子限制在由电子产生的三维阱内，然后将电子限制在由离子产生的三维阱内。
Two types of plasma equilibria are self-consistently computed for a three-electrode Malmberg-Penning trap that has an increase in the radius of a section of the center electrode. When a single species, fully non-neutral plasma is confined within the trap, equilibria are predicted in which the plasma produces a three-dimensional electric potential well. Partially non-neutral plasma equilibria are predicted to be possible by confining a second, oppositely signed plasma species within the three-dimensional well produced by the first plasma species. Conditions that are necessary for partially non-neutral plasma equilibria to be self-consistently possible are reported. A partially non-neutral plasma formed of electrons and singly charged xenon ions is then specifically considered, first with the ions confined within a three-dimensional well produced by the electrons and next with the electrons confined within a three-dimensional well produced by the ions.
