Validating neutral-beam current drive simulations in the TJ-II stellarator
Sadig Mulas, Álvaro Cappa, José Martínez-Fernández +9
In this paper, we analyze the results of neutral-beam current drive (NBCD) experiments, performed in the TJ-II stellarator, with the aim of validating the theoretical predictions.…
Oscillatory relaxation of zonal flows in a multi-species stellarator plasma
E. Sánchez, I. Calvo, J. L. Velasco +5
The low frequency oscillatory relaxation of zonal potential perturbations is studied numerically in the TJ-II stellarator (where it was experimentally detected for the first time).…
Moderation of neoclassical impurity accumulation in high temperature plasmas of helical devices
J. L. Velasco, I. Calvo, S. Satake +16
Achieving impurity and helium ash control is a crucial issue in the path towards fusion-grade magnetic confinement devices, and this is particularly the case of helical reactors, w…
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…
Particle transport after pellet injection in the TJ-II stellarator
J. L. Velasco, K. J. McCarthy, N. Panadero +17
We study radial particle transport in stellarator plasmas using cryogenic pellet injection. By means of perturbative experiments, we estimate the experimental particle flux and com…
