Simulations of ELM-induced tungsten melt flow across misaligned plasma-facing components

Nuclear Fusion
A computational fluid dynamics model of ELM-induced tungsten melt flow across a gap between misaligned plasma-facing components is validated against data from dedicated leading-edge exposures in the ASDEX Upgrade tokamak.

Dynamic and static deuterium inventory in ASDEX Upgrade with tungsten first wall [PDF]

, 2009
Hydrogen retention in the divertor tokamak ASDEX Upgrade is studied by surface analysis and gas balances methods. Comparing carbon and tung-sten plasma facing components (PFCs), the deuterium content of deposits at the divertor plates has dropped by a ...

Adaptive mapping of the plasma operational space of ASDEX Upgrade for disruption prediction

, 2012
The Self-Organizing Map is a computational method for the visualization and analysis of high-dimensional data. Self Organizing Maps have been applied to ASDEX Upgrade data to define an ordered mapping of an 8-dimensional plasma parameter space onto a ...

Characterization of ion heat conduction in JET and ASDEX Upgrade plasmas with and without internal transport barriers [PDF]

, 2003
In ASDEX Upgrade and JET, the ion temperature profiles can be described by R/L-Ti which exhibits only little variations, both locally, when comparing different discharges, andradially over a wide range of the poloidal cross-section.

Assessment of particle and heat loads to the upper open divertor in ASDEX Upgrade in favourable and unfavourable toroidal magnetic field directions

Nuclear Materials and Energy, 2019
Pairs of ASDEX Upgrade L-mode discharges with the toroidal magnetic field, BT, in the forward and reverse directions have been used to study the impact of neoclassical drifts on the divertor plasma conditions and detachment.

L- to H-mode transitions at low density in ASDEX Upgrade

, 2011
The results from ASDEX Upgrade discharges dedicated specifically to the investigation of low-density L-to-H transitions are presented. The plasmas were heated by electron cyclotron resonance heating to achieve a separation of electron and ion heat ...

Criteria and algorithms for constructing reliable databases for statistical analysis of disruptions at ASDEX Upgrade

, 2009
The present understanding of disruption physics has not gone so far as to provide a mathematical model describing the onset of this instability. A disruption prediction system, based on a statistical analysis of the diagnostic signals recorded during the
