An experimental characterization of core turbulence regimes in Wendelstein 7-X
D. Carralero, T. Estrada, E. Maragkoudakis +14
First results from the optimized helias Wendelstein 7-X stellarator (W7-X) have shown that core transport is no longer mostly neoclassical, as is the case in previous kinds of stel…

Characterization of the radial electric field and edge velocity shear in Wendelstein 7-X
D. Carralero, T. Estrada, T. Windisch +13
In this work we present the first measurements obtained by the V-band Doppler reflectometer during the second operation phase of Wendelstein 7-X to discuss the influence in the vel…

On-surface potential and radial electric field variations in electron root stellarator plasmas
J. M. García-Regaña, T. Estrada, I. Calvo +8
In the present work we report recent radial electric field measurements carried out with the Doppler reflectometry system in the TJ-II stellarator. The study focuses on the fact th…
