Experimental Test of Damping Models for n = 1 Toroidal Alfvén Eigen modes in JET

The damping rate of the n=1 TAE mode in Ohmic-heated JET plasmas has been measured and compared with the prediction of the kinetic NOVA-K code, which includes electron and ion Landau damping of the global shear-Alfvén wave field, collisional damping, and radiative damping. It was found that the calculated damping rate is too small to account for the measured value under these experimental conditions.
