Exploring the operational limits of poloidal and helical arrays of Mirnov coils in stellarators by means of a synthetic diagnostic
P. Pons-Villalonga, A. Cappa, J. Martínez-Fernández +3
A synthetic Mirnov coils diagnostic for non-axisymmetric magnetic configurations is presented and used to study the capabilities of the poloidal array of single-axis coils and the…
Observation of oscillatory radial electric field relaxation in a helical plasma
J. A. Alonso, E. Sanchez, I. Calvo +13
Measurements of the relaxation of a zonal electrostatic potential perturbation in a non-axisymmetric magnetically confined plasma are presented. A sudden perturbation of the plasma…
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 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…
