摘要

摘要: 用二维半粒子模拟程序PLASIM模拟研究了超强的S极化激光束与过稠密等离子体的相互作用过程，发现等离子体在其表面形成了波纹状结构（等离子体空泡），该现象也称为类瑞利-泰勒不稳定性；发现离子得到很大加速，其相对论动能可以达到72 MeV，并研究了高速离子的分布特点及其产生原因。

Abstract: The interaction between high power S-polarized laser and overdense plasma was investigated numerically using a 2.5 D particle code PLASIM. Both electron caviton and plasma ripple appear and the latter is just like bubbles. Ions are accelerated in the front of the bubbles, whose relativistic kinetic energy can reach 72 MeV. The distribution of energetic ions was also studied.
