Investigation of 3D effects on heat fluxes in performance-optimized island divertor configurations at Wendelstein 7-X

Investigation of 3D effects on heat fluxes in performance-optimized island divertor configurations at Wendelstein 7-X

The 3D effects on divertor heat loads have been investigated for performance-optimized island divertor configurations at Wendelstein 7-X with 3D modeling and IR camera measurements. A new high mirror configuration optimized for more stable island divertor operation due to reduced bootstrap currents...
