高能量粒子与环形阿尔芬本征模（TAE）相互作用是聚变等离子体物理研究一个很重要的问题。TAE不稳定性问题是中国聚变工程实验反应堆（CFETR）实现稳态运行所面临的重大挑战。到目前为止，在CFETR上，已经开展了高能量粒子驱动的TAE线性不稳定性问题的研究，但是，粒子碰撞对TAE非线性演化问题的研究几乎还是空白状态。本项目主要是将磁流体/动理学混合模拟程序（M3D-K）应用于集成模拟得到的CFETR完全非自感与混合两种模式中，采用自洽的方法研究粒子碰撞对TAE非线性演化的影响，特别地是包括TAE本征模结构以及频率的自洽演变。本项目的研究成果有助于理解高能量粒子与TAE之间的相互作用，从而有可能提高高能量粒子的约束性能，将积极地推动CFETR的物理和工程设计。

The interaction of energetic particles with toroidal Alfvén eigenmode (TAE) is an important issue in the study of fusion plasma physics. TAE instability is a major challenge for China Fusion Engineering Experimental Reactor (CFETR) to achieve steady-state operation. So far, studies on the linear instability of TAE driven by energetic particles have been carried out on CFETR. However, the study of nonlinear evolution of TAE with particle collision is almost blank. This project mainly applies the kinetic/MHD hybrid code (M3D-K) to the CFETR fully non-inductive and hybrid modes obtained by integrated simulation. The self-consistent method is used to investigate the effect of particle collision on TAE nonlinear evolution, in particular, include the self-consistent evolution of the TAE eigenmode structure and frequency. The research results of this project are helpful for understanding the interaction between energetic particles and TAE, which may improve the confinement performance of energetic particles, and will actively promote the physical and engineering design of CFETR.
