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…
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…
Large tangential electric fields in plasmas close to temperature screening
J. L. Velasco, I. Calvo, J. M. García-Regaña +4
Low-collisionality stellarator plasmas usually display a large negative radial electric field that has been expected to cause accumulation of impurities due to their high charge nu…
On neoclassical impurity transport in stellarator geometry
J. M. García-Regaña, R. Kleiber, C. D. Beidler +3
The impurity dynamics in stellarators has become an issue of moderate concern due to the inherent tendency of the impurities to accumulate in the core when the neoclassical ambipol…
Electron Bernstein waves emission in the TJ-II Stellarator
J. M. García-Regaña, Á. Cappa, F. Castejón +5
Taking advantage of the electron Bernstein waves heating (EBWH) system of the TJ-II stellarator, an electron Bernstein emission (EBE) diagnostic was installed. Its purpose is to in…
