Title	253: Study QH-mode with advanced fast ion diagnostics and codes
Name:	Xi Chen chenxi@fusion.gat.com	Affiliation:	General Atomics
Research Area:	Inductive Scenarios	Presentation time:	Not requested
Co-Author(s):	Bill Heidbrink, Raffi Nazikian, Gerrit Kramer, Keith Burrell, the EP group	ITPA Joint Experiment :	No
Description:	Fast ion losses associated with EHO during ELM-free QH-mode have been detected on DIII-D. But the previous measurements and interpretations are limited by the fast ion diagnostics and codes. Now, we have pitch and energy resolving Fast Ion Loss Detector (FILD) with bandwidth up to 500kHz and fast-FIDA (up to 200kHz), and full orbit calculation code SPIRAL, we can get better fast ion measurements for study of EHO, e.g. the relation with fast ion loss, the mode location, the EHO<->ELM transition.	ITER IO Urgent Research Task :	No
Experimental Approach/Plan:
Background:	Previous study in W.P. West et al. Jounal of Nuclear Materials, Volume 337, p. 420-424
Resource Requirements:	piggyback of QH-mode exp. with normal BT and Ip direction and 210R
Diagnostic Requirements:	FILD1&2, FIDA and other
Analysis Requirements:	Kinetic EFIT, TRANSP, NOVA-K, SPIRAL and other
Other Requirements:
