Title	151: ITER SS Demo Discharge Documentations
Name:	Masanori Murakami masanori_murakami@att.com	Affiliation:	Retired
Research Area:	Steady State Heating and Current Drive	Presentation time:	Not requested
Co-Author(s):	JM Park, T. Luce, J. Ferron, C. Holcomb, t. Osborne, G. Jackson, M. Okabayashi, P. Ryan, S. Diem, SSI Group	ITPA Joint Experiment :	No
Description:	ITER demonstration discharges are important data for ITER hardware heating and CD design and development of research plans. Theory-based integrated modeling for ITER SS scenario has been extensively used in ITPA-IOS group activities, such as H&CD mixes/upgrades studies. However, it needs new data based on improved hardware, diagnostic and analyses capabilities now available in DIII-D. This is a resubmission of the old ideas, but is significantly updated. In particular, it includes better more optimization, edge pedestal measurements, ITER-like off-axis NBCD, and higher ECCD capabilities.	ITER IO Urgent Research Task :	No
Experimental Approach/Plan:	1) Start with old 134372 2) Make closer to optimal ITER shape and dRsep scan 3) Error field minimization (with C and i-coils) 4) Document and evaluate f_NI, f_BS and G=betaN*H/q^2 5) Adjust timing of the high power phase at q_min=2 crossing 6) Add broadly distributed ECCD around rho=0.3=0.6 and move out 7) Higher Ip (equiv. to 11 MA) 8) Document and evaluate f_NI, f_BS and G=betaN*H/q^2 again
