Abstract

This work describes C²⁺ emission (CIII 465 nm) and flow measurements from the divertor region of a L-mode, lower-single-null plasma in DIII-D. The measurements use a coherence imaging spectrometer capable of making snapshot 2D C²⁺ flow measurements in the DIII-D lower divertor that are finely resolved in both space and time. Results show strong C²⁺ flows in the scrape-off layer towards the divertor plates. Predictions from the fluid-plasma code, UEDGE, are presented and are shown to be in good agreement with data.
