Characterization of NBI-driven shear Alfvén waves in the TJ-II stellarator using Mirnov probes and electrostatic potential fluctuation measurements
P. Pons-Villalonga, Á. Cappa, E. Ascasíbar +6
We present the first experimental measurements of the toroidal mode number of shear Alfvén waves in the TJ-II stellarator. A series of experiments were carried out in three differe…

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…

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.…
