Abstract

The Ti edge profile has been successfully measured at W7-X in an island divertor configuration using a retarding field analyzer (RFA) probe on a reciprocating manipulator. The experimental observations show that in the standard configuration, an ion temperature shoulder at the plasma boundary has been observed near the location where a sudden change of the magnetic field connection length appears in the scrape-off layer (SOL) region. In addition, the edge ion-to-electron temperature ratio has been calculated which gradually increases with the major radius and decreases with the normalized ion collisionality.
