磁约束聚变装置中离子回旋波和中性束注入联合加热的协同效应研究

单一辅助加热手段不足以满足聚变实验的需求，为提升国内磁约束聚变装置上的辅助加热效果，实现装置高参数高性能H模运行，本项目拟开展磁约束聚变装置中离子回旋波和中性束注入联合加热的协同效应研究。通过耦合离子回旋波全波方法、中性束模拟方法与（包含波扩散项和束离子慢化碰撞项）准线性Fokker-Planck方程，理论模拟研究联合加热协同效应的物理机制、产生条件、影响因素以及协同效应对加热效果、产生高能离子尾的作用。紧密联系实验，开展协同加热的优化研究，获得最大化正协同效应、提高辅助加热效率的优化方案和参数空间，为国内磁约束聚变磁置上实现更高效的辅助加热、更好的约束性能提供参考。

Single auxiliary heating method can’t meet all needs of the fusion experiments. In order to improve the auxiliary heating effect in magnetic confined fusion devices and realize the high-parameter and high-performance H-mode operation，a theoretical simulation study on synergistic effect of ICRF and NBI combined heating will be carried out in this project. By coupling ion cyclotron full-wave method, neutral beam simulation method and quasi-linear Fokker-Planck equation，the physical mechanism of the synergy effect will be theoretically analyzed，and the role of the synergistic effect on improving heating efficiency and the conditions of synergies will be investigated, the key factors will be found. The optimal methods and parameters for maximizing positive synergy effects，increasing heating efficiency will be obtained through optimization，which will provide a reference to achieve more efficient auxiliary heating and better energy confined performance in magnetic confined fusion devices.
