A survey of experimental techniques and analysis tools used at the W7-AS stellarator for the investigation of the equilibrium, stability, transport and edge plasma is given, and examples for typical results are presented. In particular, the exploitation of boundary islands for use as an `island divertor` and for the establishment of a radiating island chain are important issues. (orig.) 14 refs.
