高功率laser等离子体相互作用中的层流冲击

Laminar shocks in high power laser plasma interactions

R. A. Cairns, R. Bingham, P. Norreys, R. Trines

摘要:

本文提出了一个描述无碰撞等离子体中层流离子声结构的理论。一小部分上游离子的反射将公知的离子声孤子转换成上游具有陡峭电势梯度且下游具有振荡的结构。该理论提供了一个简单的解释的结果可以追溯到四十多年前,但更重要的是,激光产生的等离子体有关的惯性聚变和离子加速的最近的观察提供了一个解释。

英文摘要:

We propose a theory to describe laminar ion sound structures in a collisionless plasma. Reflection of a small fraction of the upstream ions converts the well known ion acoustic soliton into a structure with a steep potential gradient upstream and with downstream oscillations. The theory provides a simple interpretation of results dating back more than forty years but, more importantly, is shown to provide an explanation for recent observations on laser produced plasmas relevant to inertial fusion and to ion acceleration.
