Analytical calculations for impurity seeded partially detached divertor conditions [PDF]
Plasma Physics and Controlled Fusion, 2016 A simple analytical formula for the impurity seeded partially detached divertor operational point has been developed using 1D modelling. The inclusion of charge exchange momentum loss terms improves the 1D modelling for ASDEX Upgrade conditions and its extrapolation to larger devices.

Effects of N/Ne impurity seeding on the divertor asymmetry in HL-2A tokamak
Nuclear FusionDivertor asymmetry is a major challenge in achieving high-power, long-pulse discharges in future fusion reactors. Impurity seeding is the most common method for achieving divertor detachment in fusion devices.

Transport analysis of high radiation and high density plasmas in the ASDEX Upgrade tokamak
EPJ Web of Conferences, 2014 Future fusion reactors, foreseen in the “European road map” such as DEMO, will operate under more demanding conditions compared to present devices. They will require high divertor and core radiation by impurity seeding to reduce heat loads on divertor ...
