Implementation and verification of the avalanche source in a 3D full-f particle-in-cell model of relativistic electrons for studies of tokamak disruptions
Fiona Wouters, Hannes Bergström, Matthias Hoelzl +3
Tokamak disruptions may lead to the acceleration of some electrons to relativistic energies. These so-called runaway electrons (REs) can multiply exponentially via knock-on collisi…
Quantitative 3D non-linear simulations of shattered pellet injection in ASDEX Upgrade using JOREK
W. Tang, M. Hoelzl, P. Heinrich +16
Shattered pellet injection (SPI) as primary mitigation method for major disruptions in ITER has a large parameter space available for optimization including the total amount of inj…
Runaway electron beam formation, vertical motion, termination and wall loads in EU-DEMO
F. Vannini, V. Bandaru, H. Bergstroem +9
Runaway electron loads onto material structures are a major concern for future large tokamaks due to the efficient avalanching at high plasma currents. Here, we perform predictive…
Neural-Parareal: Dynamically Training Neural Operators as Coarse Solvers for Time-Parallelisation of Fusion MHD Simulations
S. J. P. Pamela, N. Carey, J. Brandstetter +10
The fusion research facility ITER is currently being assembled to demonstrate that fusion can be used for industrial energy production, while several other programmes across the wo…
Implementation of matrix compression in the coupling of JOREK to realistic 3D conducting wall structures
Federico Cipolletta, Nina Schwarz, Matthias Hoelzl +6
JOREK is an advanced non-linear simulation code for studying MHD instabilities in magnetically confined fusion plasmas and their control and/or mitigation. A free-boundary and resi…
Probing non-linear MHD stability of the EDA H-mode in ASDEX Upgrade
A Cathey, M Hoelzl, L Gil +11
Regimes of operation in tokamaks that are devoid of large ELMs have to be better understood to extrapolate their applicability to reactor-relevant devices. This paper describes non…
Modelling of saturated external MHD instabilities in tokamaks: a comparison of 3D free boundary equilibria and nonlinear stability calculations
Rohan Ramasamy, Guillermo Bustos Ramirez, Matthias Hoelzl +5
3D free boundary equilibrium computations have recently been used to model external kinks and edge harmonic oscillations (EHOs), comparing with linear MHD stability codes, and nonl…
Complete 3D MHD simulations of the current quench phase of ITER mitigated disruptions
F. J. Artola, A. Loarte, M. Hoelzl +3
Complete 3D simulations of the current quench phase of ITER disruptions are key to predict asymmetric forces acting into the ITER wall. We present for the first time such simulatio…
