Modelling the effect of resonant magnetic perturbations in ASDEX Upgrade with the extented MHD code XTOR-2F — •Johannes Grießhammer — Max Planck Institut für Plasmaphysik Boltzmannstraße 2, 85748 Garching bei München

Resonant magnetic perturbations (RMPs) are used in medium sized tokamaks like ASDEX Upgrade or DIII-D for the mitigation of edge localized modes (ELMs), which allows reduction of the maximum head load power on the divertor plates. The poloidal mode number spectrum of the applied RMPs is wide and penetration into the plasma of the RMP at resonant magnetic surfaces is complex due to non-ideal MHD plasma dynamics and geometry. The fully toroidal extented MHD code XTOR-2F is used to study RMP penetration, the effect of RMPs on confinement deteriorating tearing modes (TMs) and plasma rotation. Apart from RMP amplitude and mode spectrum also the influence of different plasma equilibria and plasma fluid models are (to be) studied.
