Weber, T RHoward, JohnAllen, S L2015-12-13May 6-10 21089-7623http://hdl.handle.net/1885/71269This work describes a coherence imaging spectrometer capable of making spatially resolved CIII flow measurements in the DIII-D lower divertor. The spectrometer exploits a periscope view of the plasma to produce line-of-sight averaged velocity measurements of CIII. From these chord averaged flow measurements, a 2D poloidal cross section of the CIII flow is tomographically reconstructed. Details of the diagnostic setup, acquired data, and data analysis will be presented, along with prospects for future applications.Keywords: Coherence imaging; Future applications; Line-of-sight; Spatially resolved; Flow measurement; Spectrometry; Spectrometers201210.1063/1.47283112016-02-24
