MHD activity produced by Alfvén Eigenmodes (AEs) is routinely observed in NBI-heated TJ-II plasmas <ref>A. Cappa et al, Nuclear Fusion, 61(6):066019, may 2021, and references therein</ref>. The results provided by recently installed sets of helical magnetic coils complement the previous experimental data and, together with advanced analysis tools like the 3D Lomb periodogram <ref>S. Zegenhagen, et al., Plasma Physics and Controlled Fusion, 48(9):1333–1346 (2006)</ref> allows the determination of the AEs spatial periodicity with an accuracy non reachable so far. | |||
