Measurements of the plasma edge electron density n e and temperature T e fields during application of a fast rotating, resonant magnetic perturbation RMP field show a characteristic modulation of both, ne and Te coherent to the rotation frequency of the RMP field. A phase delay between the ne(t) and Te(t) waveforms is observed and it is demonstrated that this phase delay is a function of the radius with r depending on the relative rotation of the RMP field and the toroidal plasma rotation. This provides for the first time direct experimental evidence for a rotation dependent damping of the external RMP field in the edge layer of a resistive high-temperature plasma which breaks down at low rotation and high resonant field amplitudes.
