Alpha particle driven Alfvénic instabilities in ITER post-disruption plasmas
Andrej Lier, Gergely Papp, Philipp Lauber +3
Fusion-born alpha particles in ITER disruption simulations are investigated as a possible drive of Alfvénic instabilities. The ability of these waves to expel runaway electron (RE)…
Runaway electron modelling in the self-consistent core European Transport Simulator, ETS
Gergo I. Pokol, Soma Olasz, Boglarka Erdos +12
Relativistic runaway electrons are a major concern in tokamaks. The European framework for Integrated Modelling (EU-IM), facilitates the integration of different plasma simulation…
Spatiotemporal analysis of the runaway distribution function from synchrotron images in an ASDEX Upgrade disruption
M. Hoppe, L. Hesslow, O. Embreus +14
Synchrotron radiation images from runaway electrons (REs) in an ASDEX Upgrade discharge disrupted by argon injection are analyzed using the synchrotron diagnostic tool SOFT and cou…
Kinetic modelling of runaway electron generation in argon-induced disruptions in ASDEX Upgrade
K. Insulander Björk, G. Papp, O. Embreus +8
Massive material injection has been proposed as a way to mitigate the formation of a beam of relativistic runaway electrons that may result from a disruption in tokamak plasmas. In…
Self-consistent modeling of runaway electron generation in massive gas injection scenarios in ASDEX Upgrade
O. Linder, E. Fable, F. Jenko +4
We present the first successful simulation of a induced disruption in ASDEX Upgrade from massive material injection (MMI) up to established runaway electron (RE) beam, thus coverin…
Moment-Preserving and Mesh-Adaptive Reweighting Method for Rare-Event Sampling in Monte-Carlo Algorithms
C. U. Schuster, T. Johnson, G. Papp +4
We present novel roulette schemes for rare-event sampling that are both structure-preserving and unbiased. The boundaries where Monte Carlo markers are split and deleted are placed…
