Title	357: GAM eigenmode 2D structure
Name:	Guiding Wang wangg@fusion.gat.com	Affiliation:	University of California, Los Angeles
Research Area:	Turbulence & Transport	Presentation time:	Not requested
Co-Author(s):	Peebles, Rhodes, McKee, Yan	ITPA Joint Experiment :	No
Description:	To obtain radial and poloidal amplitude and propagation structure of GAMs in poloidal ExB flow, density, and electron temperature in L-mode plasmas, and compare with radial eigenmode theories	ITER IO Urgent Research Task :	No
Experimental Approach/Plan:	L-mode, reduced size plasma vertically scanned over 40 cm
Background:	GAM is an important player in edge turbulence and transport. GAM eigenmodes have been observed on DIII-D. A 2D (radial and poloidal) characterization is needed for a better understanding of GAM and its interaction with turbulence.
Resource Requirements:	ECH and NBI.
Diagnostic Requirements:	all turbulence and profile diagnostics.
Analysis Requirements:	lots
Other Requirements:
