Impact of magnetic islands on plasma flow and turbulence in W7-X
T. Estrada, E. Maragkoudakis, D. Carralero +13
The effect of magnetic islands on plasma flow and turbulence has been experimentally investigated in the stellarator W7-X. Magnetic configurations with the 5/5 magnetic island posi…
Radial electric field and density fluctuations measured by Doppler reflectometry during the post-pellet enhanced confinement phase in W7-X
T. Estrada, D. Carralero, T. Windisch +13
Radial profiles of density fluctuations and radial electric field, , have been measured using Doppler reflectometry during the post-pellet enhanced confinement phase achieved,…
On the role of density fluctuations in the core turbulent transport of Wendelstein 7-X
D. Carralero, T. Estrada, E. Maragkoudakis +19
A recent characterization of core turbulence carried out with a Doppler reflectometer in the optimized stellarator Wendelstein 7-X (W7-X) found that discharges achieving high ion t…
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…
First Results from an Event Synchronized -- High Repetition Thomson Scattering System at Wendelstein 7-X
Hannes Damm, Ekkehard Pasch, Andreas Dinklage +16
The Wendelstein 7-X (W7-X) Thomson scattering (TS) diagnostic was upgraded to transiently achieve kilohertz sampling rates combined with adjustable measuring times. The existing Nd…
