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…
Quantitative Magnetohydrodynamic Modelling of Flux Pumping in ASDEX Upgrade
Haowei Zhang, Matthias Hölzl, Isabel Krebs +9
The sawtooth-free hybrid scenario has been achieved recently in ASDEX Upgrade (AUG) with applied non-inductive current sources and auxiliary heating [A. Burckhart et al 2023 Nucl.…
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…
Testing of the new JOREK stellarator-capable model in the tokamak limit
Nikita Nikulsin, Matthias Hoelzl, Alessandro Zocco +2
In preparation for extending the JOREK nonlinear MHD code to stellarators, a hierarchy of stellarator-capable reduced and full MHD models has been derived and tested. The derivatio…
Non-linear extended MHD simulations of type-I edge localised mode cycles in ASDEX Upgrade and their underlying triggering mechanism
Andres Cathey, M. Hoelzl, K. Lackner +9
A triggering mechanism responsible for the explosive onset of edge localised modes (ELMs) in fusion plasmas is identified by performing, for the first time, non-linear magnetohydro…
Numerical study of tearing mode seeding in tokamak X-point plasma
Dmytro Meshcheriakov, Matthias Hoelzl, Valentin Igochine +11
A detailed understanding of island seeding is crucial to avoid (N)TMs and their negative consequences like confinement degradation and disruptions. In the present work, we investig…
