Ultrahigh neutral pressures in the sub-divertor of the Large Helical Device
Nuclear FusionIn the Large Helical Device (LHD) a low temperature mode (LTM) of the helical divertor was discovered. It combines particle detachment and very large sub-divertor pressures up to 1.4 Pa. During the LTM, the electron temperature in the divertor was in the

Healing of magnetic islands in stellarators by plasma flow
, 2011 Recent experiments from the Large Helical Device indicate that plasma flow can play a primary role in ‘healing’ vacuum magnetic islands in stellarators.

A model for Alfvén-eigenmode-induced transport of fast ions in stellarators
Nuclear FusionA novel model for Alfvén-eigenmode-induced transport of fast ions in stellarators is introduced. A variety of reduced transport models exists for tokamaks, but nothing comparable currently exists for stellarators.

Comprehensive Analysis on the Role of Helical Movement of the Magnetic Axis in Stellarators
, 2014 The physical confinement properties of stellarators are analyzed for the neo-classical transport and the magnetic well. Three typical concepts of stellarators (LHD, Wendelstein 7-X and TJ-II) are compared in terms of the helical movement of cross ...

Exposure of tungsten heavy alloys at high thermal loads in LHD
Nuclear Materials and EnergyTungsten has been considered a plasma-facing material in a future fusion reactor because of its low sputtering yield and low fuel retention. It has been examined in several tokamaks.

International Astronomical Union Colloquium, 1980 Important progress in our understanding of stellar chromospheres has occurred in the past few years as a result of new observations, developments in spectral line formation theory, and the application of that theory to the construction of detailed model chromospheres.
