Title	49: Turbulent transport in detached divertor
Name:	Jose Boedo boedo@fusion.gat.com	Affiliation:	University of California, San Diego
Research Area:	Divertor & SOL Physics	Presentation time:	Not requested
Co-Author(s):	D. Rudakov, C. Tsui, J. Watkins	ITPA Joint Experiment :	No
Description:	Detached divertors are known to feature enhanced transport (not only atomic-based dissipation) that spreads particle and heat loads. But little is known about the details and we propose to systematically investigate the turbulence and transport properties of detached divertors	ITER IO Urgent Research Task :	Yes
Experimental Approach/Plan:	Detach the lower and upper divertors (not simultaneously) and evaluate rms levels of density and potentials and if possible (geometry-limited) the turbulent transport.
Background:	divertor detachment is a solution for large heat and particle fluxes into the divertor components. There is still much unknown about the detached divertor dynamics and transport. In particular, enhanced transport helps to further spread heat and particle loads. So we propose to investigate that mechanism
Resource Requirements:	DIII-D, lowish power NBI (2 MW), ECH (1-2 MW)
Diagnostic Requirements:	Xpoint and midplane scanning probes, floor probes, turbulence diagnostics (BES, reflectometry, etc)
Analysis Requirements:	diagnostic analysis and if possible fluid and turbulence simulatiosn (UEDGE, SOLPS, BOUT)
Other Requirements:	--
