Effect of mode structure variation on fast particle transport in hybrid-kinetic simulations — •Thomas Hayward-Schneider and Philipp Lauber — Max-Planck-Institut für Plasmaphysik, Garching, Germany

Perturbative modelling of Alfvén eigenmodes (AEs) using the nonlinear perturbative drift-kinetic initial value code Hagis and the linear gyrokinetic eigenvalue code Ligka is introduced. We present the steps to couple these two codes, with a goal of non-/semi- perturbative, nonlinear simulations of AEs. Towards this aim, we show a benchmark of a prescribed, time-dependent mode structure in Hagis. We introduce ITER scenarios for study, and observe that the AE resonance locations are highly sensitive to the magnetic profiles.
