Overview of Recent Physics Results from NSTX
Authors: S.M. Kaye, et al.
Abstract: NSTX is currently being upgraded to operate at twice the toroidal eld and plasma current (up to 1 T and 2 MA), with a second, more tangentially aimed neutral beam for current and rotation control, allowing for pulse lengths up to 5 s. Recent NSTX physics analyses have addressed topics that will allow NSTX-Upgrade to achieve the research goals critical to a Fusion Nuclear Science Facility. These include producing stable, 100% non-inductive operation in high performance plasmas, assessing Plasma Material Interface (PMI) solutions to handle the high heat loads expected in the next-step devices and exploring the unique Spherical Torus (ST) parameter regimes to advance predictive capability.
