Postdoc in plasma edge turbulence modeling (x/f/m)

High-fidelity gyrokinetic modeling of the scrape-off layer is essential in predicting and understanding confinement physics in fusion devices. By contributing to the further development of the Gkeyll code - through the implementation of finite-Larmor-radius effects or improvement of the solver for magnetic fluctuations - the candidate will lay the groundwork for and then conduct state-of-the-art studies, advancing our understanding of a crucial plasma region. This work will be performed in close collaboration with the Gkeyll Team at PPPL and experimentalists at DIFFER and/or WEST.

Tasks:

• improve and extend the gyrokinetic code Gkeyll
• test the new code against known solutions and other codes
• perform simulations in different geometries to assess impurity dynamics and transport in the scrape-off layer
• compare simulation results to experimental measurements on WEST Required background:
• experience in using the gyrokinetic framework
• knowledge of plasma edge/SOL physics

Optional background:

• knowledge of how heavy impurities impact turbulence and transport
• experience with edge gyrokinetic codes (e.g., Gkeyll or GENE-X)
• experience with edge fluid codes
