Quasi-single-stage optimization for permanent magnet stellarators

Nuclear Fusion
Advanced stellarators are typically optimized in two stages. The plasma equilibrium is optimized first, followed by the design of coils/permanent magnets.

Oscillatory relaxation of zonal flows in a multi-species stellarator plasma

, 2018
The low frequency oscillatory relaxation of zonal potential perturbations is studied numerically in the TJ-II stellarator (where it was experimentally detected for the first time).

Density profiles in stellarators: an overview of particle transport, fuelling and profile shaping studies at TJ-II

Nuclear Fusion
We provide an overview of activities carried out at the TJ-II stellarator for improving our understanding of- and developing plasma physics models for particle density profiles in stellarators.

Relativistic neoclassical radial fluxes in the 1/nu regime

, 2013
The radial neoclassical fluxes of electrons in the 1/nu regime are calculated with relativistic effects taken into account and compared with those in the non-relativistic approach.

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.
