Title	342: Investigation of Core Poloidal Rotation Anomaly Change at ITG -> TEM transition
Name:	Won Ha Ko none	Affiliation:	ZZZ
Research Area:	Plasma Rotation	Presentation time:	Not requested
Co-Author(s):	B. Grierson, S.H. Ko, J.M.Kwon, Y.J.Shi, P.H.Diamond, S.H.Hahn, W. Solomon	ITPA Joint Experiment :	Yes
Description:	This experiment will study the change of the core poloidal rotation anomaly at ITG ->TEM transition and the role of turbulence driven poloidal Reynolds stress in the anomaly change. With strong ECH heating on H-mode plasmas with nulled toroidal rotation, it is expected that turbulence population changes from ITG to TEM. Measurement of poloidal rotation will reveal the departure of the rotation value from the neoclassical prediction and how the departure changes according to the turbulence population change.	ITER IO Urgent Research Task :	Yes
Experimental Approach/Plan:
Background:
Resource Requirements:	6 Gyrotrons, balanced NBIs half run day might be desired.
Diagnostic Requirements:	Standard profile diagnostics (ne, Ti, Te, rotation, Er profiles) Nice to have main ion CER Density and temperature fluctuation diagnostics (BES and ECEI) High speed CER for toroidal and poloidal rotation Thomson scattering and microwave reflectometry for density profile, DBS, PCI
Analysis Requirements:
Other Requirements:
