Simulation Study of Interaction between Alfven Eigenmodes and Energetic Particles

采用混合模拟方法研究了聚变等离子体中高能粒子与Alfven本征模的相互作用。阐明了环形Alfven本征模（TAE模）/反向剪切Alfven本征模与高能粒子相互作用的性质，非线性MHD效应对TAE不稳定性和TAE爆发演化的影响，高能粒子驱动测地声学模的线性性质和非线性频率啁啾，以及Alfven本征模与高能粒子在ITER等离子体中的输运。

We studied the interaction between Alfven eigenmodes and energetic particles in fusion plasmas with the hybrid simulation of energetic particles interacting with a magnetohydrodynamics (MHD) fluid. We clarified the properties of the interaction between toroidal Alfven eigenmode (TAE mode)/reversed shear Alfven eigenmode and energetic particles, the nonlinear MHD effects on the evolution of TAE instability and TAE bursts, the linear properties and the nonlinear frequency chirping of the energetic- particle driven geodesic acoustic modes, and the Alfven eigenmodes and the energetic-particle transport in the ITER plasmas.
