Physik in unserer Zeit, Volume 52, Issue 3, Page 116-122, May 2021., 2021 Der Tokamak ASDEX Upgrade am Max‐Planck‐Institut für Plasmaphysik in Garching ist seit dreißig Jahren in Betrieb. In dieser Zeit wurde die Fusionsanlage immer weiter ausgebaut und verbessert. Inzwischen hat man zahlreiche gut diagnostizierte Szenarien für den Plasmabetrieb erarbeitet.

Analysis and expansion of the quasi-continuous exhaust (QCE) regime in ASDEX Upgrade
Nuclear Fusion, 2023 The quasi-continuous exhaust (QCE) regime, formerly known as either type-II ELM or small ELM regime is studied in ASDEX Upgrade. The regime is a natural type-I ELM-free H-mode.

Probing non-linear MHD stability of the EDA H-mode in ASDEX Upgrade [PDF]
Nuclear Fusion, 2023 Regimes of operation in tokamaks that are devoid of large edge localised modes have to be better understood to extrapolate their applicability to reactor-relevant devices.

Experimental evidence of magnetic flux pumping in ASDEX upgrade
Nuclear Fusion, 2023 In high- β scenarios with on-axis co-current electron cyclotron current drive, which normally lowers q _0 below unity, the absence of sawteeth suggests the involvement of an additional current redistribution mechanism beyond neoclassical current ...

Overview of initial negative triangularity plasma studies on the ASDEX Upgrade tokamak
Nuclear Fusion, 2022 An overview of results of negative triangularity (NT) studies from the ASDEX Upgrade tokamak (AUG) is given. Moderate values of the triangularity in the range of δ _average ≈ −0.2 have been obtained.

The X-Point radiating regime at ASDEX Upgrade and TCV
Nuclear Materials and Energy, 2023 Future fusion reactors require a safe, steady-state divertor operation. With deep divertor detachment, which is typically induced by impurity seeding, the radiation concentrates in a small region at the X-point or on closed flux surfaces above the X ...

Complex structure of turbulence across the ASDEX Upgrade pedestal [PDF]
Journal of Plasma Physics, 2023 The theoretical investigation of relevant turbulent transport mechanisms in H-mode pedestals is a great scientific and numerical challenge. In this study, we address this challenge by global, nonlinear gyrokinetic simulations of a full pedestal up to the
