Associate Research Scientist - Computational Stellarator Physics

Overview

The Princeton Plasma Physics Laboratory seeks outstanding candidates for postdoctoral position in the area of computational stellarator physics. The successful candidate will play a leading role in developing a state-of-the-art, fully three-dimensional version of the fluid turbulence code SOLEDGE3X, as part of PPPL’s international collaboration with CEA, France. The final goal will be modeling self consistently plasma and impurity transport in the edge of a magnetic fusion device, tokamaks and stellarators alike. The candidate will also perform numerical simulations with both the existing and improved versions of the SOLEDGE3X code, coupled with the Dust Injector Simulator (DIS) code, of powder injection experiments to be performed both in the WEST tokamak and the W7-X stellarator, benchmarking the simulation results against experimental measurements, providing interpretation the observed phenomena and guiding the planning of additional experiments.

Responsibilities

The successful candidate will be responsible for:

• Benchmarking SOLEDGE3X simulations against experimental data from the WEST tokamak (20%)

• Extending the SOLEDGE3X code to a fully 3D version, including 3D magnetic geometry, working closely with CEA collaborators (50%)

• Benchmarking fully 3D SOLEDGE3X simulations against experimental measurements from the W7-X stellarator (20%)

• Publishing and presenting research in peer reviewed journals and at international conferences (10%)

To accelerate scientific progress, the candidate will work closely with the SOLEDGE3X developing team, located in CEA, Cadarache, France, where the WEST tokamak is also located. The ability for on-site presence will greatly facilitate both code development and access to experimental data for code validation. The successful candidate will collaborate at PPPL in Princeton, New Jersey and with the CEA Cadrache team.

Qualifications

Applicants should hold a Ph.D. in plasma physics, engineering, computational science or relevant field(s). Experience in developing numerical code, preferably fortran, is required. Preference will be given to candidates with experience in modeling edge and scrape-off layer plasma, or more broadly in modeling magnetic fusion devices (tokamaks and stellarators). Knowledge of plasma turbulence processes and plasma-wall interaction processes is a plus.
