本文讨论了一种可能的超强激光等离子体中异常离子加热的新机制。该机制是基于由快速电子束驱动的电子双流不稳定性激发，并共振衰减为离子声波。这些低频波随后被密集等离子体中的离子碰撞强烈地抑制。该模型简单地解释了近年来在PW能级激光实验中观察到的大块离子居群的优先加热现象。
A possible new mechanism for anomalous ion heating in ultra-intense laser plasmas is considered here. This mechanism is based on the excitation of an electron two-stream instability that is driven by the fast electron beam and resonantly decays into ion-acoustic waves. These low frequency waves are then strongly damped by the ion collisions in the dense plasma. The model gives a simple explanation for the preferential heating of the bulk ion population observed in recent laser experiments in the petawatt (PW) regime.
