Rotation dependence of a phase delay between plasma edge electron density and temperature fields due to a fast rotating, resonant magnetic perturbation field
Rotation dependence of a phase delay between plasma edge electron density and temperature fields due to a fast rotating, resonant magnetic perturbation field
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, n(e) and T-e coherent to the rotation frequency of the RMP field. A phase delay Phi between the...

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, n(e) and T-e coherent to the rotation frequency of the RMP field. A phase delay Phi between the n(e)(t) and T-e(t) waveforms is observed and it is demonstrated that this phase delay Phi is a function of the radius with Phi(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.
