Towards non-linear hybrid simulations of the interaction between energetic particles and the plasma in realistic tokamak geometry — •Felix Antlitz, Xin Wang, and Matthias Hoelzl — Max Planck Institute for Plasma Physics, Garching b. M., Germany

Future burning plasma experiments will feature a high supra-thermal particle pressure which strongly interact with magneto-hydrodynamic instabilities. To describe these dynamics accurately in simulations, realistic tokamak geometry, the self-consistent evolution of the plasma equilibrium, and a full-f treatment of the energetic particle population are needed. This contribution describes developments towards this goal based on the non-linear MHD code JOREK, in which a hybrid mode for energetic particles had recently been introduced based on a pressure coupling and tested linearly. The non-linear evolution of fishbone instabilities is foreseen as one of the first applications.
