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…
Synthetic Diagnostic Modeling for Plasma Tomography: Geometry Matrix Computation Methods and Impact of Model Accuracy
D. Hamm, G. Partesotti, C. Theiler +1
Tomographic emissivity reconstruction from plasma diagnostics data relies on a synthetic model mapping the plasma emissivity to the measured signals. The model, referred to as a ge…
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…
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…
Variability of MHD Instabilities in Benign Termination of High-Current Runaway Electron Beams in the JET and DIII-D Tokamaks
C. F. B. Zimmermann, C. Paz-Soldan, G. Su +14
Benign termination, in which magnetohydrodynamic (MHD) instabilities deconfine runaway electrons (REs) following hydrogenic injections, is a promising strategy for mitigating dange…
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,…
