Staff Research Physicist-Modeling RF Heating Program
PPPL/NSTX-U has an opening at the research staff level for a physicist to develop and apply state of the art theoretical and computational models in support of the laboratory's RF heating program on NSTX-U and, through collaborations, on DIII-D, C-Mod, EAST and KSTAR devices. An ability to work closely with RF physicists at other institutions is required, since a number of these models are currently developed through the laboratory's participation in DOE's SciDAC programs. Fluency in modern FORTRAN programming and familiarity with UNIX operating systems is required, as well as the ability to work with large scale computational tools that are undergoing physics upgrades by a number of rf physicists. Currently the models in use or under development include both ray tracing and full wave approaches for the RF wave fields and Fokker- Planck codes for the evolution of rf-driven modifications to co-resonant fast particle distributions, though it is anticipated that extensions of these models to include particle-in-cell type techniques will become increasingly important.
The person chosen must have completed a Ph.D. in plasma physics or a closely related discipline. Preferred candidates will have had at least 3 years of post-graduate experience in developing RF theory and computational models, and will have demonstrated the ability to work with experimentalists on detailed comparisons of model predictions with experimental observations. Expertise in RF heating in frequencies ranges from the ion cyclotron up through the electron cyclotron regime also is highly desirable, given the strong collaborative component of the research to be conducted.
