激光惯性约束聚变动理学效应研究进展

Research progress of kinetic effects in laser inertial confinement fusion

摘要: 动理学效应的研究是近年来激光惯性约束聚变领域的研究热点，有助于理解实验结果和传统流体模拟之间的偏差。间接驱动黑腔中等离子体的温度、密度跨越多个量级且靶丸组分复杂，在局域的高温低密度区域，粒子的非平衡效应开始变得显著，可能会间接影响内爆性能。对ICF领域动理学效应的概念和部分进展做了简要综述。

Abstract: In recent years, the study of kinetic effects is a hot issue in the field of laser inertial confinement fusion, which helps to understand the deviation between experimental results and traditional fluid simulation. The temperature and density of the plasma in indirect-drive hohlraum span multiple orders of magnitude, and the composition of capsule is complex. In the local high temperature and low density region, the thermal non-equilibrium effect of particles becomes significant, which may indirectly affect the implosion performance. In this paper, the concept and some progress of kinetic effects in the ICF field are briefly reviewed.
