 note = {A local island divertor (LID) has been proposed for the edge plasma control of the Large Helical Device (LHD), and its functions and effects on edge plasmas have been studied in detail.  Although the LHD edge plasma will primarily be controlled by a closed full helical divertor, the LID will be used as an alternative.  The advantage of the LID over the helical divertor is technical ease of the hydrogen pumping because of its toroidally localized recycling.  A significant feature of the LID is high overall pumping efficiency of    is greater than or equal to 30%, which is the key in realizing high temperature divertor operation, leading to a significant energy confinement improvement.},
