A. Soukhanovskii, NSTX FY2011 Research Forum, 17 March 2011, Princeton, NJ 2 of 9 Boundary Physics TSG priorities are defined by DOE and NSTX Milestones FY2011 DOE Joint Research Target: Conduct experiments on major fusion facilities to improve the understanding of the physics mechanisms responsible for the structure of the pedestal and compare with the predictive models described in the companion theory milestone. R(11-3): Assess very high flux expansion divertor operation NSTX-U design needs ITPA participation, ITER design and physics needs Career development: post-doctoral research Slide 3 V. A.
