Evolution of SPI-induced disruptions in ASDEX Upgrade
P. Heinrich, G. Papp, S. Jachmich +23
Disruptions are a major concern for future fusion reactors based on the tokamak principle. To ensure machine protection, the thermal loads and vessel forces that arise during disru…
Modelling of shattered pellet injection experiments on the ASDEX Upgrade tokamak
Ansh Patel, Akinobu Matsuyama, Gergely Papp +13
In a shattered pellet injection (SPI) system the penetration and assimilation of the injected material depends on the speed and size distribution of the SPI fragments. ASDEX Upgrad…
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.…
Radiated energy fraction of SPI-induced disruptions at ASDEX Upgrade
Paul Heinrich, Gergely Papp, Stefan Jachmich +15
Future large tokamaks will operate at high plasma currents and high stored plasma energies. To ensure machine protection in case of a sudden loss of plasma confinement (major disru…
Axisymmetric predictions for mitigated and vertically unstable disruptions in ITER with runaway electrons
V. Bandaru, M. Hoelzl, F. J. Artola +2
We present two-dimensional global simulations of mitigated and vertically unstable disruptions in ITER in the presence of runaway electrons. An elongated plasma in free-boundary eq…
Runaway Electron Dynamics in ITER Disruptions with Shattered Pellet Injections
Oskar Vallhagen, Lise Hanebring, Javier Artola +6
This study systematically explores the parameter space of disruption mitigation through shattered pellet injection in ITER with a focus on runaway electron dynamics, using the disr…
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…
