Abstract
X-ray imaging measurements have contributed to studies of the plasma equilibrium, plasma fluctuations, impurity radiation and impurity transport effects in the advanced stellarator Wendelstein W7-AS (R=2 m, a=17 cm). In addition, time resolved electron temperature profiles are deduced from X-ray intensity ratios according to the two absorber foil method. The plasma is generated and heated by fundamental and 2{sup nd} harmonic ECRH (P{le}800 kW at 70 GHz). Neutral beam injection heating (P{le}1.5 MW) was applied also, assisted by D{sub 2} pellet injection. (author) 8 refs., 7 figs.
