The impact of heating power on radial heat transport in W7-X
B. Ph. van Milligen, U. Hoefel, M. Hirsch +3
The understanding of the outward radial transport of heat in magnetic confinement fusion devices is a priority for the development of economically viable fusion reactors. Here, we…
The impact of rational surfaces on radial heat transport in TJ-II
B. Ph. van Milligen, J. H. Nicolau, L. García +3
In this work, we study the outward propagation of temperature perturbations. For this purpose, we apply an advanced analysis technique, the Transfer Entropy, to ECE measurements pe…
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…
The causal impact of magnetic fluctuations in slow and fast L-H transitions at TJ-II
B. Ph. van Milligen, T. Estrada, B. A. Carreras +6
This work focuses on the relationship between L-H (or L-I) transitions and MHD activity in the low magnetic shear TJ-II stellarator. It is shown that the presence of a low order ra…
