On Viscous Damping and Rotation in Low-Shear Stellarators

one of the main results of the Wendelstein 7-AS stellarator (major radius 2 m, average plasma radius 0' l8 m, magnetic field 2.5 T' low shear) is the achievement of the H-mode confinement in ECRand NBl-heated plasmas. The features of the H-mode are similar to those of a tokamak: reduction of the Ho-emission, onset of poloidal rotation anda30vo improvement of the energy confinement time, which i...

Spatial distribution of turbulence in the Wendelstein 7-AS stellarator

In this paper measurements of short wavelength electron density fluctuations using collective scattering of infrared light are presented. The Wendelstein 7-AS (W7-AS) stellarator (Renner H et al 1989 Plasma Phys. Control. Fusion 31 1579) and the diagnostic are briefly described. A series of plasma discharges with reproducible confinement transitions was created by ramping up the plasma current....

Island divertor experiments on the Wendelstein 7-AS stellarator

A promising new operational regime on the Wendelstein stellarator W7-AS has been discovered, fulfilling the conditions of optimal core behavior in combination with edge parameters suitable for successful divertor scenarios. This regime, the high density H-mode (HDH), displays no systematically evident mode activity, and is edge localized mode (ELM)-free. It is extant above a power-dependent thr...

From W7-X to a HELIAS fusion power plant: motivation and options for an intermediate-step burning-plasma stellarator

As a starting point for a more in-depth discussion of a research strategy leading from Wendelstein 7-X to a HELIAS power plant, the respective steps in physics and engineering are considered from different vantage points. The first approach discusses the direct extrapolation of selected physics and engineering parameters. This is followed by an examination of advancing the understanding of stel...
