Resonant features of energy and particle transport during application of resonant magnetic perturbation fields at TEXTOR and DIII-D
In this paper, results of a direct comparison of TEXTOR and DIII-D experiments with resonant magnetic perturbation (RMP) fields are presented. This comparison of resistive L-mode plasmas at TEXTOR with highly conductive H-mode plasmas at DIII-D is useful to identify generic physics mechanisms during...

| description | In this paper, results of a direct comparison of TEXTOR and DIII-D experiments with resonant magnetic perturbation (RMP) fields are presented. This comparison of resistive L-mode plasmas at TEXTOR with highly conductive H-mode plasmas at DIII-D is useful to identify generic physics mechanisms during application of RMP fields with a strong field line pitch angle alignment in the plasma edge. A reduction in the pedestal electron pressure p sub(e) with increasing extension of the vacuum modelled stochastic layer and p sub(e) recovery with decreasing layer width is found caused by a q sub(95) resonant reduction in the edge (0.8 < [psi] sub(N) < 0.95) electron temperature T sub(e)(q sub(95)) on both devices. We show the potential to reduce the RMP induced particle pump out by fine tuning of the RMP spectral properties. At low resonant field amplitudes enhanced particle confinement is seen in high-field side limited L-mode discharges on both devices while higher resonant field amplitudes yield particle pumps out. |
