Title:Energetic Particle interaction with TAE in tokamak
Abstract: A reduced model to study nonlinear, resonant interaction of energetic particles with Alfven waves in tokamak geometry has been built where the mode structures of Alfven modes such as TAEs are fixed and mode amplitudes and phases are evolved due to wave particle interaction between energetic particles and Alfven waves. The initial simulation results compare well with NOVA-K code and M3D-K code for the linear growth rate of an n=1 TAE mode. Work is in progress to benchmark the code in the nonlinear regime and to investigate the nonlinear saturation of multiple Alfven modes driven by fast ion.
