The Princeton Plasma Physics Laboratory (PPPL) seeks to fill a full-time position for a researcher to work on international collaborations focusing on 3D magnetic fields and on core-edge integrated tokamak scenarios. The successful candidate will develop advanced optimization schemes for 3D magnetic fields to stabilize the edge plasma while simultaneously minimizing transport losses and the peak heat flux to plasma facing components (PFCs). The candidate will design and validate optimized 3D tokamak scenarios for long-pulse operation in KSTAR, and will participate in 3D field physics studies in COMPASS-U, NSTX-U, and DIII-D. Long-term, the candidate will prepare for ITER experiments and contribute to the development of ITER optimization strategies for 3D fields. The Princeton Plasma Physics Laboratory is a world-class fusion energy research laboratory managed by Princeton University for the U.S. Department of Energy’s Office of Science. PPPL is dedicated to developing the scientific and technological knowledge base for fusion energy. The Laboratory advances the fields of fusion energy and plasma physics research to develop the scientific understanding and key innovations needed to realize fusion as an energy source for the world.
Responsibilities
The successful candidate will integrate predictive 3D MHD and transport models and simulation to plan for and optimize 3D fields in tokamak scenarios. The candidate will perform both reduced model and full 3D field MHD simulations to predict MHD instability free operating windows from the core to the edge for the entire duration of the tokamak pulse including the early and late transient phase including the L-H and H-L transition. The candidate will develop a workflow to predict thermal and particle losses from the plasma as well as the heat flux to the divertors (40%).
The candidate is expected to conduct extensive data analysis and participate in experimental campaigns particularly on long pulse tokamak facilities such as KSTAR. Broad experience and knowledge on diagnostics are essential to reconstruct profiles and 3D equilibria and to compare the transport and edge modeling results with fluctuation and imaging diagnostics. The candidate will also propose and perform new predict-first experiments to validate the predictive optimizations in various tokamak devices (40%)
Another important responsibility for the candidate is to strongly contribute to the international and domestic collaborations on 3D tokamak optimizations. The candidate will design and analyze new 3D coils, configurational optimizations, and baseline scenarios with integrated 3D control in future plasma operations in various tokamaks such as COMPASS-U and NSTX-U in preparation for ITER (20%).
