Title	353: Correlation length of electron temperature turbulence measurement and comparison with simulations
Name:	Guiding Wang wangg@fusion.gat.com	Affiliation:	University of California, Los Angeles
Research Area:	Turbulence & Transport	Presentation time:	Not requested
Co-Author(s):	Rhodes, Peebles, Holland	ITPA Joint Experiment :	No
Description:	Investigate radial correlation length of electron temperature turbulence using CECE system and compare with gyrokinetic simulations.	ITER IO Urgent Research Task :	No
Experimental Approach/Plan:	Steady-state L-modes, density scan and heating power scan
Background:	The turbulence correlation length provides a robust alternative to fluctuation levels to compare with turbulence modeling predictions. Due to the much larger thermal noise superimposed in the electron temperature fluctuations, it has been challenging to obtain a radial correlation length of electron temperature turbulence using the CECE measurement. A dedicated experiment will allow for a detailed investigation.
Resource Requirements:	most gyrotrons and NB sources
Diagnostic Requirements:	CECE and all other turbulence and profile diagnostics
Analysis Requirements:	lots
Other Requirements:
