Abstract

A promising new plasma operational regime on the Wendelstein stellarator W7-AS has been discovered. It is extant above a threshold density and characterized by flat density profiles, high energy and low impurity confinement times, and edge- localized radiation. Impurity accumulation is avoided. Quasistationary discharges with line-averaged densities (n) over bar (e) to 4x10(20) m(-3) , radiation levels to 90% , and partial plasma detachment at the divertor target plates can be simultaneously realized. Energy confinement is up to twice that of a standard scaling. At B-t=0.9 T , an average beta value of 3.1% is achieved. The high (n) over bar (e) values allow demonstration of electron Bernstein wave heating using linear mode conversion.
