Evolution of SPI-induced disruptions in ASDEX Upgrade

Nuclear Fusion
Disruptions are a major concern for future fusion reactors based on the tokamak principle. To ensure machine protection, the thermal loads and vessel forces that arise during disruptions have to be mitigated reliably.

Mapping of the ASDEX Upgrade Operational Space using Clustering Techniques

, 2007
Two clustering techniques are used to map ASDEX Upgrade high-dimensional operational space. The produced mapping exploits the similarities of the data by grouping similar data items together, allowing to identify characteristic regions for plasma ...

Migration and deposition of 13C in the full-tungsten ASDEX Upgrade tokamak [PDF]

, 2010
The migration of carbon in low-density, low-confinement plasmas of ASDEX Upgrade was studied by injecting 13C into the main chamber of the torus at the end of the 2007 experimental campaign. A selection of standard tungsten-coated lower-divertor and main-

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
