AXUV synthetic diagnostic for ASDEX Upgrade and its application for SPI simulations
Ferenc Lengyel, Weikang Tang, Matthias Hölzl +14
We introduce an Absolute eXtended UltraViolet (AXUV) diode-based camera forward-modelling tool to support the validation of mitigated disruption simulations and the interpretation…
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…
Simulation of Shattered Pellet Injections with Plasmoid Drifts in ASDEX Upgrade and ITER
O. Vallhagen, L. Antonsson, P. Halldestam +7
Pellet injection is an important means to fuel and control discharges and mitigate disruptions in reactor-scale fusion devices. To accurately assess the efficiency of these applica…
Reduced kinetic modelling of shattered pellet injection in ASDEX Upgrade
Peter Halldestam, Paul Heinrich, Gergely Papp +8
Plasma-terminating disruptions represent a critical outstanding issue for reactor-relevant tokamaks. ITER will use shattered pellet injection (SPI) as its disruption mitigation sys…
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.…
Bayesian optimization of massive material injection for disruption mitigation in tokamaks
Istvan Pusztai, Ida Ekmark, Hannes Bergström +5
A Bayesian optimization framework is used to investigate scenarios for disruptions mitigated with combined deuterium and neon injection in ITER. The optimization cost function take…
