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

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 ...

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.

The high field side high density region in SOLPS-modeling of nitrogen-seeded H-modes in ASDEX Upgrade

Nuclear Materials and Energy, 2017
The understanding of divertor physics and the evolution of divertor detachment is crucial for developing the capability to model power exhaust in current experiments and reliably predict it for future fusion devices.

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 ...
