An upper pressure limit for low-Z benign termination of runaway electron beams in TCV
M Hoppe, J Decker, U Sheikh +17
We present a model for the particle balance in the post-disruption runaway electron plateau phase of a tokamak discharge. The model is constructed with the help of, and applied to,…
Non-linear MHD modelling of shattered pellet injection in ASDEX Upgrade
W. Tang, M. Hoelzl, M. Lehnen +11
Shattered pellet injection (SPI) is selected for the disruption mitigation system in ITER, due to deeper penetration, expected assimilation efficiency and prompt material delivery.…
Integrated Data Analysis and Validation
R. Fischer, A. Bock, S. S. Denk +4
A major challenge in nuclear fusion research is the coherent combination of data from heterogeneous diagnostics and modelling codes for machine control and safety as well as physic…
3D MHD modelling of plasmoid drift following massive material injection in a tokamak
M. Kong, E. Nardon, D. Bonfiglio +5
Mechanisms of plasmoid drift following massive material injection are studied via 3D non-linear MHD modelling with the JOREK code, using a transient neutral source deposited at the…
Plasmoid drift and first wall heat deposition during ITER H-mode dual-SPIs in JOREK simulations
D. Hu, F. J. Artola, E. Nardon +6
The heat flux mitigation during the Thermal Quench (TQ) by the Shattered Pellet Injection (SPI) is one of the major elements of disruption mitigation strategy for ITER. It's effici…
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…
