Prevention of core particle depletion in stellarators by turbulence
H. Thienpondt, J. M. García-Regaña, I. Calvo +11
In reactor-relevant plasmas, neoclassical transport drives an outward particle flux in the core of large stellarators and predicts strongly hollow density profiles. However, this t…
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…
Suppression of core turbulence by profile shaping in Wendelstein 7-X
A. v. Stechow, O. Grulke, Th. Wegner +23
In the Wendelstein 7-X magnetic confinement experiment, a reduction of turbulent density fluctuations as well as anomalous impurity diffusion is associated with a peaking of the pl…
Validating fast-ion wall-load IR analysis-methods against W7-X NBI empty-torus experiment
S. Äkäslompolo, P. Drewelow, Y. Gao +17
The first neutral beam injection (NBI) experiments in Wendelstein 7-X (W7-X) stellarator were conducted in the summer of 2018. The NBI system is used to heat the magnetically confi…
Validating the ASCOT modelling of NBI fast ions in Wendelstein 7-X stellarator
S. Äkäslompolo, P. Drewelow, Y. Gao +37
The first fast ion experiments in Wendelstein 7-X were performed in 2018. They are one of the first steps in demonstrating the optimised fast ion confinement of the stellarator. Th…
