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…
