ASSESSMENT OF GLOBAL STELLARATOR CONFINEMENT: STATUS OF THE INTERNATIONAL STELLARATOR CONFINEMENT DATABASE

Further exploration of confinement trends in the evolving International Stellarator Confinement Database is reported. The impact of configurations on confinement is confirmed, and the performance close to operational limits is discussed. Model comparison techniques allow for tests of physical models against data. Correlations of configuration-describing parameters against an empirical confinement enhancement factor are investigated.
