在托卡马克装置中，高能量粒子可以激发出各种不稳定性，这些不稳定性会导致高能量粒子的大量输运以及损失。因此，对于高能量粒子物理的研究是托卡马克物理的一项重要内容。本项目拟紧密结合具备丰富辅助加热手段的EAST托卡马克实验装置，使用国际知名大规模并行程序M3D-K和GEM开展高能量粒子激发不稳定性以及高能量粒子输运相关的数值模拟工作。项目拟以重现EAST实验中观测到的高能量粒子激发的不稳定性为基础，为EAST相关实验提供物理分析，并为EAST放电的近一步优化提供参考依据。另外，本项目也拟针对未来的CFETR装置开展alpha粒子激发的阿尔芬本征模的预研工作，为现阶段CFETR装置的设计提供相关参考依据。

In tokamaks, energetic particles can drive various instabilities, and these instabilities can in turn induce significant energetic particle transport and associated losses. As a result, investigation of energetic particle physics is crucial for tokamak physics. This project plans to carry out numerical simulations of energetic particle driven instabilities and fast particle transport in the EAST tokamak with various auxiliary heating methods, using two international famous codes M3D-K and GEM. The simulation results will be compared to experimental measurements in the EAST directly, and this project aims to provide further physical analysis and improvements for the EAST experiment. In addition, this project also plans to carry out simulations of Alfvén eigenmodes driven by alpha particles in the future CFETR device, in order to provide useful guidance for the current design of the CFETR tokamak.
