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…
Electrostatic gyrokinetic simulations in Wendelstein 7-X geometry: benchmark between the codes stella and GENE
A. González-Jerez, P. Xanthopoulos, J. M. García-Regaña +6
The first experimental campaigns have proven that, due to the optimization of the magnetic configuration with respect to neoclassical transport, the contribution of turbulence is e…
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…
Turbulent impurity transport simulations in Wendelstein 7-X plasmas
J. M. García-Regaña, M. Barnes, I. Calvo +8
A study of turbulent impurity transport by means of quasilinear and nonlinear gyrokinetic simulations is presented for Wendelstein 7-X (W7-X). The calculations have been carried ou…
