Abstract
A review of experiments with ECRH- and NBI-heated plasmas in W7-AS is given. Global results of W7-AS are summarized. Particular emphasis is put on electron cyclotron current drive, comparative analysis of electron heat transport derived from power balance and perturbative studies, and particle transport under combined ECRH- and NBI-heating conditions. The role of the plasma boundary field configuration as a necessary condition for the existence of the H-mode in W7-AS is discussed and first observations of coherent global Alfven eigenmodes and turbulent temperature fluctuations in the plasma core are reported.Keywords
