Abstract

The large helical device (LHD), now under construction, is a heliotron/torsatron device with a closed divertor system. The edge LHD magnetic structure has been studied in detail. A peculiar feature of the configuration is the existence of edge surface layers, a complicated three-dimensional magnetic structure. However, it does not seem to hamper the expected divertor functions. As a confinement improvement scheme in LHD, we have proposed a high temperature divertor plasma operation in which a divertor plasma with a temperature of a few keV, generated by efficient pumping, leads to the confinement improvement. Conceptual designs of the LHD divertor components are under way.
