The LHD experiment has just begun. A scenario is presented for LHD divertor
experiments. It includes development of LHD divertor components particular
ly efficient pumping system, local island divertor as a closed pumped diver
tor, simultaneous achievement of H-mode and radiative cooling (SHC operatio
n) as an PI-mode approach in the helical device, high temperature divertor
plasma operation for enhancement of the energy confinement. (C) 1999 Elsevi
