| Research Abstract |
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.
