在德拜长度小于等离子体尺寸和等离子体尺寸小于阱尺寸的条件下，讨论了Penning或Paul阱中非中性等离子体的静电模.在这个限制的等离子体形状是球形和解析解存在的所有模式。Paul阱等离子体模的解是Penning阱等离子体模的一个特例。给出了一些低阶四极模的简单推导。实验测量了激光冷却Be ~+离子在Penning阱中的等离子体的模频率，结果与理论计算符合得很好
The electrostatic modes of a non-neutral plasma confined in a Penning or Paul (M trap are discussed in the limit that the Debye length is small compared to the plasma dimensions and the plasma dimensions are small compared to the trap dimensions. In this limit the plasma shape is spheroidal and analytic solutions exist for all of the modes. The solutions for the modes of a Paul-trap plasma are a special case of the modes of a Penning-trap plasma. A simple derivation of some of the low-order quadrupole modes is given. Experimental measurements of these mode frequencies on plasmas of laser-cooled Be + ions in a Penning trap agree well with the calculations
