ALFVEN WAVE PROPAGATION AND SAFETY FACTOR PROFILE MEASUREMENTS IN THE TCA TOKAMAK
An expanded beam laser imaging diagnostic based on the phase contrast method is used on TCA to measure the radial profiles of density oscillations of driven kinetic Alfven waves created by resonant mode conversion at the shear Alfven wave resonance layers. Beyond the experimental confirmation of theoretical predictions, the detection of the Alfven wave resonance is exploited to yield the safety factor profile of the discharge.
