Ultrahigh neutral pressures in the sub-divertor of the Large Helical Device

Nuclear Fusion
In 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

A model for Alfvén-eigenmode-induced transport of fast ions in stellarators

Nuclear Fusion
A 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.

Exposure of tungsten heavy alloys at high thermal loads in LHD

Nuclear Materials and Energy
Tungsten 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.

MONKES: a fast neoclassical code for the evaluation of monoenergetic transport coefficients in stellarator plasmas

Nuclear Fusion
MONKES is a new neoclassical code for the evaluation of monoenergetic transport coefficients in stellarators. By means of a convergence study and benchmarks with other codes, it is shown that MONKES is accurate and efficient.

Physics of magnetic confinement fusion

EPJ Web of Conferences, 2013
Fusion is the energy source of the universe. The local conditions in the core of the Sun allow the transfer of mass into energy, which is finally released in the form of radiation.

Stellarators with enhanced tritium confinement and edge radiation control

Nuclear Fusion
A stellarator design is described with the purpose of achieving three goals: (1) enhance the confinement time of tritium. (2) Have a sufficient density of high- Z impurities to radiate the thermal power escaping from the core while having an extremely ...
