97. Non-linear free boundary MHD simulations of ELM suppression by resonant magnetic perturbations in ASDEX Upgrade plasmas (I.11)

Verena Mitterauer (Max Planck Institute for Plasma Physics)

03/10/2023, 14:00

Invited

The presentation will introduce the principles of suppressing edge localized modes (ELMs) by external magnetic perturbations (RMPs). It will explain models that allow the description of the processes and highlight recent developments. Direct comparisons between simulations and experiments will be shown, and an outlook to the application for future machines like ITER will be given.

Oral

An accumulation of heavy impurities in the tokamak core is detrimental for its performance and can lead to disruption of the plasma. In smaller to medium size tokamaks the effective neoclassical transport in the pedestal is radially inwards [3]. In larger tokamaks---e.g. ITER--- where the temperature gradient is higher, the neoclassical transport is predicted to be outwards. The models are...

72. Global Alfvénic modes excitation in Ohmic Tokamak plasmas following magnetic reconnection events (O.10)

Oral

A possible triggering mechanism of Alfvén waves (AWs) in tokamak plasmas, based on localized perturbations induced by magnetic reconnection events, is discussed in the framework of nonlinear viscoresistive 3D MHD modeling.
