30 Jahre ASDEX Upgrade

open access: yesPhysik 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.

Overview of ASDEX Upgrade results [PDF]

open access: yesNuclear Fusion, 2011
The ASDEX Upgrade programme is directed towards physics input to critical elements of the ITER design and the preparation of ITER operation, as well as addressing physics issues for a future DEMO design. After the finalization of the tungsten coating of the plasma facing components, the re-availability of all flywheel-generators allowed high-power ...

Dust investigations at ASDEX Upgrade [PDF]

open access: yesPhysica Scripta, 2009
Investigations on dust in the full tungsten divertor tokamak, ASDEX Upgrade, are summarized. Newly designed collectors are used to distinguish plasma-produced dust from other kinds of debris. Whereas submicron particles are often tungsten spheres, larger ones are agglomerates from tungsten in a boron/carbon matrix.

SOLPS-ITER simulations of an X-point radiator in the ASDEX Upgrade tokamak

open access: yesNuclear Fusion, 2022
The X-point radiator (XPR) is an attractive scenario that may contribute to solving the power exhaust problem in future fusion devices. The 2D transport code SOLPS-ITER was applied to reproduce the experimentally measured plasma condition with an XPR in ...

Observation and Modelling of the Onset of Parametric Decay Instabilities during Gyrotron Operation at ASDEX Upgrade [PDF]

open access: yesEPJ Web of Conferences, 2019
We investigate parametric decay instabilities (PDIs) occurring for gyrotron radiation near the upper hybrid resonance at the ASDEX Upgrade tokamak.

Experiments and non-linear MHD simulations of hot vertical displacement events in ASDEX-Upgrade

open access: yesPlasma Physics and Controlled Fusion, 2023
Hot vertical displacement events (VDEs) are one of the worst case scenarios for high-current tokamaks as they are associated with large heat loads and electro-magnetic forces.

Turbulence characterization during the suppression of edge-localized modes by magnetic perturbations on ASDEX Upgrade

open access: yesNuclear Fusion, 2023
We study localized edge turbulence in the ASDEX Upgrade tokamak that appears if resonant magnetic perturbations (RMP) are applied to suppress edge localized modes (ELMs) in the high confinement mode.

Overview of physics studies on ASDEX Upgrade [PDF]

open access: yesNuclear Fusion, 2019
Abstract The ASDEX Upgrade (AUG) programme, jointly run with the EUROfusion MST1 task force, continues to significantly enhance the physics base of ITER and DEMO. Here, the full tungsten wall is a key asset for extrapolating to future devices.

Physics of the electric field in the scrape-off layer in ASDEX Upgrade L-mode discharges and comparison to experiments

open access: yesNuclear Materials and Energy, 2022
The electric field in the Scrape-Off Layer (SOL) of fusion plasmas is a key quantity affecting the local plasma transport and possibly also the overall plasma confinement. However, the physics determining the SOL electric field is experimentally not well

Overview of ASDEX Upgrade results [PDF]

open access: yesNuclear Fusion, 2003
Recent results from the ASDEX Upgrade experimental campaigns 2001 and 2002 are presented. An improved understanding of energy and particle transport emerges in terms of a ‘critical gradient’ model for the temperature gradients. Coupling this to particle diffusion explains most of the observed behaviour of the density profiles, in particular, the ...
