Title	238: Direct Measurement of NTV Torque
Name:	Nikolas Logan ncl2128@columbia.edu	Affiliation:	Columbia University
Research Area:	Stability & Disruption Avoidance	Presentation time:	Requested
Co-Author(s):	E.J. Strait, J.K. Park, A. Cole	ITPA Joint Experiment :	No
Description:	This proposal is for the direct measurement of NTV torque using the integrated Maxwell stress tensor at the vessel wall. The goal is to test the hypothesis that the fundamental mechanism of NTV momentum exchange between the plasma and surrounding world is electromagnetic.	ITER IO Urgent Research Task :	No
Experimental Approach/Plan:
Background:
Resource Requirements:	n=3 I-coils on top of EFC for low rotation. Co and counter neutral beams.
Diagnostic Requirements:
Analysis Requirements:	Sufficient plasma response signal in the magnetics and decent rotation scan must be ensured. The integral torque from the maxwell stress tensor can be checked between shots for an eye-ball sense of how clean the data looks.
Other Requirements:
