Title	266: Understand resistive wall mode control physics in low-q95 plasmas
Name:	Jeremy Hanson hansonjm@fusion.gat.com	Affiliation:	Columbia University
Research Area:	Inductive Scenarios	Presentation time:	Not requested
Co-Author(s):	J. Bialek, A. Garofalo, G. Jackson, M. J. Lanctot, E. Lazarus, J. P. Levesque, P. Martin, M. E. Mauel, G. A. Navratil, M. Okabayashi, C. Paz-Soldan, P. Piovesan, E. Strait, F. Turco, A. Turnbull	ITPA Joint Experiment :	No
Description:	Unstable resistive wall modes (RWMs) and the loss of active RWM control are problems that lead to disruptions in plasmas with q95 < 2. This experiment would address the control issues, and if successful, lead to a feedback-stabilized q95 < 2 discharge or a determination of the feedback limit (eg, the maximum open-loop growth rate or minimum q95 that can be stabilized using feedback).	ITER IO Urgent Research Task :	No
Experimental Approach/Plan:
Background:
Resource Requirements:
Diagnostic Requirements:	Magnetics, MSE, CER, Thomson scattering, ECE radiometer, density interferometer
Analysis Requirements:	Determination of RWM feedback system transfer function and feedback modeling, prior to experiment.
Other Requirements:
