理论上使用两种独立的方法检查包含负离子的准中性等离子体中的离子尾流场。这里描述的两种分析基于最初的假设，即驱动离子束可以被注入到漂移等离子体或静止等离子体中。两种方法都预测离子尾流场可能是振荡的、恒定的或呈指数下降。推导了离子尾流场振荡频率周期的公式。提出了不同特性的驱动离子束对尾流场激发和调制的影响。
Ion wake fields in a quasineutral plasma that contains negative ions are theoretically examined using two independent approaches. The two analyses described here are based on the initial assumption that a driving ion bunch may be injected into either a drifting plasma or a stationary plasma. Both methods predict that the ion wake fields may be oscillatory, constant, or decrease exponentially. A formula for the period of the oscillation frequency of the ion wake field is derived. Effects of driving ion bunches with different characteristics on the wake field excitation and modulation are presented.
