Collision operator for moderately coupled plasma and MHD transport equations for high-current relativistic Electron beam in the presence of ackground over-dense plasma in ICF fast ignition

核聚变能研究是当今重要的科学前沿领域之一。近十多年来，聚变科学和技术己取得的巨大进步，当前正计划分别在建造中的属于惯性约束聚变(ICF)途径的国家点火装置(NIF)和磁约束聚变(MCF)途径的国际热核聚变实验堆(ITER)上演示点火，获得自持燃烧等离子体。聚变能研究开始向聚变能电站的前景迈进。本论文围绕受控热核聚变这一宏伟目标，在理论上对惯性约束核聚变研究中两个重要的物理问题一中等藕合强度等离子体中的碰撞算子和ICF快点火中高能电子磁流体模型输运方程组作了深入研究。The research of fusion energy is one of the most important science branches and of great interest. Recent advances in the science and technology of fusion energy have dramatically improved the prospect for practical fusion power. The goal of a self-sustaining, burning fusion plasma is planed to be achieved both in inertial fusion with the National Ignition Facility and in magnetic fusion with the international ITER experiment. In this paper, two interesting physical problems about fusion science has been investigated, which are collision operator for moderately coupled plasma and magnetohydrodynamic (MHD) transport equations for high current propagation in overdense plasmas in fast ignition (Fl)
