Exhaust-rate measurements in a divertor with large mirror ratio

Technical Report ·
OSTI ID:5012353
The parallel ion fluid velocity in the scrape-off layer of a poloidal divertor is observed to vary inversely with the mirror ratio in the divertor's throat for ratios ranging from 1 to 5, in good agreement with models developed for bundle divertors. The density variation on a diverted field line also agrees qualitatively with the models, but the observed electric field does not.
