Mitigation of Initial Transients in Total-f Gyrokinetic Turbulence Simulations Using Neoclassically Relaxed Distribution Function
S. Ku, R. Hager, C. S. Chang +2
The paper introduces an initialization method for total‑f gyrokinetic turbulence simulations that uses a neoclassically relaxed particle distribution, reducing large initial transi…

Gyrokinetic prediction of core tungsten peaking in a WEST plasma with nitrogen impurities
J. Dominski, P. Maget, O. Manas +7
Tungsten peaking is predicted in the core of a WEST plasma with total-f gyrokinetic simulations, including both collisional and turbulent transport. This prediction is validated wi…
