Abstract

Reversed shear Alfvén eigenmodes in the non-circular triangularity induced Alfvén eigenmode frequency range are observed during the current ramp-up phase in JET discharges. Ideal magnetohydrodynamical calculations are able to reproduce the observed Alfvén eigenmode spectra accurately. It was found that these modes come into existence because of the plasma elongation.
