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…
The role of magnetic islands in modifying long range temporal correlations of density fluctuations and local heat transport
B. Ph. van Milligen, T. Estrada, L. Garcia +7
This work explores the relation between magnetic islands, long range temporal correlations and heat transport. A low order rational surface () was purposely scanned outw…
