Edge turbulence measurements in L-mode and I-mode at ASDEX Upgrade
Physics of Plasmas, 2022 The I-mode confinement regime is promising for future reactor operation due to high energy confinement without high particle confinement. However, the role of edge turbulence in creating I-mode's beneficial transport properties is still unknown.

Fusion Materials Development at Forschungszentrum Jülich
Advanced Engineering Materials, Volume 22, Issue 6, June 2020., 2020 In fusion material research, the focus has been twofold‐plasma facing and structural materials allowing to withstand the extreme conditions such as neutron bombardment and high heat fluxes. In this contribution, the background for the choice of tungsten as first wall material is given and the advanced materials developed at Forschungszentrum Jülich ...

Impact of drifts in the ASDEX upgrade upper open divertor using SOLPS‐ITER
Contributions to Plasma Physics, Volume 60, Issue 5-6, June-July 2020., 2020 Abstract SOLPS‐ITER L‐mode‐like simulations with the full set of currents and drift velocities activated, and fluid neutrals have been carried out to interpret experimental results obtained in AUG. Drifts are critical to quantitatively reproduce the experimental results; however, simulations without drifts can also reproduce some trends qualitatively ...

Nuclear Materials and Energy, 2019 Previous simulation results for the tokamak ASDEX Upgrade have shown that Magnetic Perturbation (MP) fields could lead to a decrease of the peak heat flux onto the divertor targets. However, experimentally, such a decrease has not been observed.

The separatrix operational space of ASDEX Upgrade due to interchange-drift-Alfvén turbulence
Nuclear Fusion, 2021 The efficient operation of a tokamak is limited by several constraints, such as the transition to high confinement or the density limits occurring in both confinement regimes. These particular boundaries of operation are derived in terms of a combination

The Deuterium Inventory in ASDEX Upgrade [PDF]
, 2007 The deuterium inventory in ASDEX Upgrade was determined by quantitative ion beam analysis techniques and SIMS for different discharge campaigns between the years 2002 and 2005. ASDEX Upgrade was a carbon dominated machine during this phase. Full poloidal

I-mode pedestal relaxation events in the Alcator C-Mod and ASDEX Upgrade tokamaks [PDF]
Nuclear Fusion, 2021 In some conditions, I-mode plasmas can feature pedestal relaxation events (PREs) that transiently enhance the energy reaching the divertor target plates.
