DIII-D demonstrates elimination of RMP induced inter-ELM electron temperature lobes in the divertor at high densities

•  At moderate core densities lobes in the electron temperature extend to the divertor plates

•  At higher core densities these lobes move up, away from the targets –  Trends can be reproduced by

modeling with EMC3-Eirene

Partial detachment of the divertor may be used to eliminate non-axisymmetric heat flux

Briesemeister EX/7-3Rb

Resonant magnetic perturbations (RMPs), used for ELM control, can cause local, non-axisymmetric peaks in divertor heat flux
