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…
A model for the fast evaluation of prompt losses of energetic ions in stellarators
J. L. Velasco, I. Calvo, S. Mulas +4
A good understanding of the confinement of energetic ions in non-axisymmetric magnetic fields is key for the design of reactors based on the stellarator concept. In this work, we d…
Gyrokinetic simulations in stellarators using different computational domains
E. Sánchez, J. M. García-Regaña, A. Bañón Navarro +9
In this work, we compare gyrokinetic simulations in stellarators using different computational domains, namely, flux tube, full-flux-surface, and radially global domains. Two probl…
Turbulent transport of impurities in 3D devices
J. M. García-Regaña, M. Barnes, I. Calvo +5
A large diffusive turbulent contribution to the radial impurity transport in Wendelstein 7-X (W7-X) plasmas has been experimentally inferred during the first campaigns and numerica…
Experimental confirmation of efficient island divertor operation and successful neoclassical transport optimization in Wendelstein 7-X
Thomas Sunn Pedersen, the W7-X Team
We present recent highlights from the most recent operation phases of Wendelstein 7-X, the most advanced stellarator in the world. Stable detachment with good particle exhaust, low…
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…
