Edge plasma diagnostics on W7-AS and ASDEX-Upgrade using fast Li beams
Knowledge of the impurity concentration and temperature in the core plasma gradient region as well as the SOL is a vital element on the road to documenting and understanding the physics of L- and H-mode transport and the transport barrier itself. To this end, the LI-beam diagnostic capabilities on W7-AS and ASDEX-Upgrade have been expanded to include the measurement of radial profiles of impurity ion density and temperature via charge-exchange-spectroscopy. After presenting the method of Li-CXS this paper describes the experimental set-up on W7-AS as well as ASDEX-Upgrade and presents first results on both experiments.
