The effect of divertor closure on the impurity stagnation point in detached L-mode discharges on DIII-D

The effect of divertor closure on the impurity stagnation point in detached L-mode discharges on DIII-D

This paper presents experimental measurements of the location of the impurity flow stagnation point in the scrape-off-layer (SOL) of a tokamak plasma. Coherence imaging of carbon-2+ emission (465 nm) is used to track the main-chamber impurity velocity of DIII-D L-mode plasmas with B×∇B out of the di...
