Impedance measurements and magnetic probes are used to study driven global Alfvén eigenmodes in a small tokamak. The probes measure the field amplitudes in the outer region of the plasma, complementing earlier laser measurements in the plasma interior. An approximate analytic model is used to help determine mode numbers. The measured field profiles and impedance values are found to compare favorably with the predictions of a cylindrical, kinetic theory calculation. Measured widths of resonances are consistently found to be larger than theoretical predictions. [ABSTRACT FROM AUTHOR] |
