  • 介于惯性约束聚变与磁约束聚变之间的磁化靶聚变技术, 可能是一种实现纯聚变更低廉更有效的途径. 磁化靶聚变一般分为三个过程: 形成过程、传输过程和内爆压缩过程. 利用二维磁流体力学模拟程序MPF-2D, 对反场构形的传输过程进行了理论研究. 结果显示, 反场构形在传输过程中必须外加适当的磁场, 使得其内外磁压平衡, 才能维持其拓扑结构并进行稳定的传输. 还对初始磁压、传输磁场以及线圈间隙对反场构形传输过程的影响进行了详细的分析.

     

    Magnetized target fusion (MTF) is an alternative approach to fusion between traditional inertial confinement fusion and magnetic confinement fusion. It involves three processes: the formation of target plasma, the translation of target plasma, and compression process of implosion. In this paper, the translation process is studied with a two-dimensional magneto-hydrodynamic code MPF-2D, and the result shows that it is necessary to add a proper magnetic field in the translation process of field reversed configuration in order to maintain its topological structure. The effects of initial magnetic pressure, translation magnetic field, and the gap between coils are studied in detail.
