Report on first results of ASDEX Upgrade operation with the Lyra divertor
Preliminary results of the first two months of ASDEX Upgrade operation with the new Lyra divertor (DV-II) are presented and compared to those obtained with the previous divertor configuration (DV-I). Emphasis is placed on issues which, according to common knowledge, might be related to the edge/divertor geometry, in particular upper density limits, H mode characteristics, particle control and impurity behaviour. The experimental facts are complemented by B2-Eirene modelling results. Remarkable changes in core magnetohydrodynamic (MHD) behaviour are also included, but their origin is not yet clear.
