On the mechanism of Pedestal Relaxation Events -- Insights gained by turbulence simulations with GRILLIX
Christoph Pitzal, Andreas Stegmeir, Tim Happel +7
Pedestal Relaxation Events (PREs) appear in I-mode discharges close to the I-H transition. Although they show certain similarities with Edge Localised Modes (ELMs), i.e. periodic e…
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…
Quantitative Magnetohydrodynamic Modelling of Flux Pumping in ASDEX Upgrade
Haowei Zhang, Matthias Hölzl, Isabel Krebs +9
The sawtooth-free hybrid scenario has been achieved recently in ASDEX Upgrade (AUG) with applied non-inductive current sources and auxiliary heating [A. Burckhart et al 2023 Nucl.…
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…
The separatrix operational space of next-step fusion experiments: From ASDEX Upgrade data to SPARC scenarios
Thomas Eich, Thomas Body, Michael Faitsch +13
Fusion power plants require ELM-free, detached operation to prevent divertor damage and erosion. The separatrix operational space (SepOS) is proposed as a tool for identifying acce…
Correlation of the L-mode density limit with edge collisionality
Andrew Maris, Cristina Rea, Alessandro Pau +10
The "density limit" is one of the fundamental bounds on tokamak operating space, and is commonly estimated via the empirical Greenwald scaling. This limit has garnered renewed inte…
Characteristics of the Alfvénic activity during the current quench in ASDEX Upgrade
P. Heinrich, G. Papp, Ph. Lauber +7
ASDEX Upgrade has developed multiple massive gas injection (MGI) scenarios to investigate runaway electron (RE) dynamics. During the current quench of the MGI induced disruptions,…
A quasi-continuous exhaust scenario for a fusion reactor: the renaissance of small edge localized modes
G. F. Harrer, M. Faitsch, L. Radovanovic +13
Tokamak operational regimes with small edge localized modes (ELMs) could be a solution to the problem of large transient heat loads in future fusion reactors because they provide q…
New high-confinement regime with fast ions in the core of fusion plasmas
A. Di Siena, R. Bilato, T. Görler +12
The key result of the present work is the theoretical prediction and observation of the formation of a new type of transport barrier in fusion plasmas, called F-ATB (fast ion-induc…
