"Initial observations of divertor heat flux mitigation in the Super-X divertor configuration in MAST Upgrade"

J. R. Harrison T. Farley G. M. Fishpool A. Kirk B. Lipschultz J. Lovell F. Militello D. Moulton P. Ryan R. Scannell A. J. Thornton K. Verhaegh L. Xiang

The benefits of an optimised Super-X divertor configuration in mitigating the steady-state power and particle fluxes to the surfaces of the MAST Upgrade divertor have been quantified by performing a detailed comparison with a conventional divertor for the first time.  In otherwise identical plasmas with conventional and Super-X divertor configu…

"Understanding the effects of super-X divertor configuration on optimizing the operational space in DEMO"

L. Xiang F. Militello D. Moulton F. Subba L. Aho-Mantila D. Coster M. Wensing T. Lunt M. Wischmeier H. Reimerdes

The SOLPS-ITER simulations of European DEMO reactor, with 450 MW of power to be exhausted, show an increased operational space compared to the conventional single-null configuration. Using a reduced model with fluid neutrals and bundled impurities, we assessed the existence and the boundaries of operational space for DEMO with the conventional sing…
