Overview The successful candidate will conduct experiments, modeling and analysis in the area of core and edge physics. In addition, the candidate will support and maintain the operation of the NSTX-U charge exchange recombination spectroscopy and edge rotation diagnostics, which measure ion temperature, flow velocity, and impurity density profiles. The candidate will be based onsite in Princeton NJ, and will participate and contribute in the area of core and edge physics on a range of devices: NSTX-U, LTX-beta, ST40, and possibly MAST-U. Travel to support collaborative experimental research on offsite facilities may be required.   The Princeton Plasma Physics Laboratory is a world-class fusion energy research laboratory managed by
