Non-linear Simulations of MHD Instabilities in Tokamaks Including Eddy Current Effects and Perspectives for the Extension to Halo Currents
M. Hoelzl, G. T. A. Huijsmans, P. Merkel +9
The dynamics of large scale plasma instabilities can strongly be influenced by the mutual interaction with currents flowing in conducting vessel structures. Especially eddy current…
Coupling JOREK and STARWALL for Non-linear Resistive-wall Simulations
M. Hoelzl, P. Merkel, G. T. A. Huysmans +6
The implementation of a resistive-wall extension to the non-linear MHD-code JOREK via a coupling to the vacuum-field code STARWALL is presented along with first applications and be…
Flux pumping and bifurcated relaxations of helical core in 3D magnetohydrodynamic modelling of ASDEX Upgrade plasmas
H. Zhang, M. Hoelzl, I. Krebs +12
Flux pumping was achieved in recent hybrid scenario experiments in the ASDEX Upgrade (AUG) tokamak, which is characterized by a sawtooth-free helical quiescent state and the anomal…
Scalings and Plasma Profile Parameterisation of ASDEX High Density Ohmic Discharges
P. J. Mc Carthy, K. S. Riedel, O. J. W. F. Kardaun +2
High density (), low (), Ohmic discharges from the ASDEX experiment is analysed statistically. Bulk parameter scalings and…
MHD simulations of small ELMs at low triangularity in ASDEX Upgrade
A. Cathey, M. Hoelzl, G. Harrer +9
The development of small- and no-ELM regimes for ITER is a high priority topic due to the risks associated to type-I ELMs. By considering non-linear extended MHD simulations of the…
Comparing spontaneous and pellet-triggered ELMs via non-linear extended MHD simulations
A. Cathey, M. Hoelzl, S. Futatani +8
Injecting frozen deuterium pellets into an ELMy H-mode plasma is a well established scheme for triggering edge localized modes (ELMs) before they naturally occur. Based on an ASDEX…
