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.

Compact shunts for the upper divertor of ASDEX Upgrade [PDF]

AIP Advances
The compact shunts that are mounted in the upper divertor of ASDEX Upgrade are now operational and measure the thermocurrents generated by the temperature difference between the two target plates of the upper divertor cassette.

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

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.

The physics of ballooning-limited ELM-free regimes in EUROfusion tokamaks

Nuclear Fusion
The development of operational scenarios without large Type-I ELMs is of utmost importance for the stable operation and longevity of future tokamaks. The EUROfusion tokamak exploitation program has therefore made the understanding of ELM-free regimes a ...

Neoclassical impurity transport in the tokamak transport barrier and pedestal with SOLPS-ITER

Nuclear Fusion
New neoclassical corrections are implemented in the SOLPS-ITER code package and can be used for modeling with drifts. These corrections are introduced to obtain standard neoclassical impurity flux in the core for non-steep main ion density and ...

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 ...
