Title: Nonlinear simulation of interaction between fast ion and TAE
Abstract: A reduced model to study nonlinear, resonant interaction of energetic particles with TAEs in tokamak geometry has been presented.Including Shafranov shift and introducing flux coordinates with realistic equilibrium geometry, we get good agreement with NOVA-k, which computes stability of global MHD and non-MHD modes in the presence of energetic particles.
Collision effect has also been added in code, and we observe frequency sweeping when marginal instability occurs.
