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…
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…
Nonlinear MHD simulation of core plasma collapse events in stellarators
Yasuhiro Suzuki, Shimpei Futatani, Joachim Geiger
The core collapse events observed in a stellarator experiment are studied by a three-dimensional nonlinear MHD simulations. In the low magnetic shear configuration like the Wendels…
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…
Parallel impurity dynamics in the TJ-II stellarator
J A Alonso, J L Velasco, I Calvo +12
We review in a tutorial fashion some of the causes of impurity density variations along field lines and radial impurity transport in the moment approach framework. An explicit and…
