Title	322: ELM pacing in low torque, electron heated ITER baseline
Name:	Wayne Solomon solomon@fusion.gat.com	Affiliation:	General Atomics
Research Area:	Inductive Scenarios	Presentation time:	Not requested
Co-Author(s):	G. Jackson, F. Turco, N. Commaux, L. Baylor	ITPA Joint Experiment :	No
Description:	The aim of this experiment is to test the performance of pellet pacing in low torque, electron dominant heated ITER baseline plasmas.	ITER IO Urgent Research Task :	No
Experimental Approach/Plan:	This should be an extension to eg proposal #118, which starts with an ECH dominant IBS plasma (progressing from #150480) and extends to lower q95. If this is successful, pellet pacing should be deployed to integrate an additional important aspect of the ITER baseline scenario (ELM control). The impact on confinement and stability should be investigated.
Background:	Pellet pacing has successfully been used in ITER like discharges. However, these have been highly rotating, NBI heated discharges. Work in 2012 has established low torque IBS plasmas, and has begun to explore dominant EC heating. A logical extension is to include ELM control. RMP suppression has proven challenging at low rotation, presumably owing to undesirable field penetration deep in the plasma.
Resource Requirements:	1 day expt, 6 gyrotorons with NTM control, 210 beams, pellets
