 note = {"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 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 temperature of a few kev, generated by efficient pumping, leads to the confinement improvement. Conceptual designs of the LHD divertor components are under way."},
