Experimental Observation of Non- Resonant Toroidal Rotation Braking with a Magnetic Perturbation Field on JET

The paper presents an analysis of toroidal rotation profiles under the influence of a non-axisymmetric magnetic perturbation in JET plasmas with n = 1 or n = 2 mode numbers of the perturbing fields. A scaling of the torque with (dB/B)a is derived from the experimental data and torque profiles are compared to predictions from Neoclassical Toroidal Viscosity (NTV) theory.
