Abstract

A local island divertor (LLD) was installed on the Compact Helical System (CHS) to demonstrate the principle of LLD and to study its effects on the edge plasma. The particle flow was observed to be guided to the back side of the externally created magnetic island along field lines, and pumped out by a cryogenic pump with high pumping efficiency. As a result, a factor of about 2 reduction in the average core density was seen compared with non-LID discharges at the same gas puff rate. In addition to the demonstration of these fundamental divertor functions, we observed a modest improvement of energy confinement, which couldbe due to the edge plasma control by the local island divertor.
