Abstract
We report new results of full-torus gyrokinetic simulations of electrostatic turbulence with Elmfire spanning from the magnetic axis to the scrape-off layer (SOL). The new implementation presented here uses the logical boundary condition, which allows for improved stability and flexibility in terms of geometry. We simulate the full plasma of the FT-2 tokamak (Ioffe Institute, Saint-Petersburg, Russian Federation), with two poloidal limiters defining the SOL. We recover expected results in the SOL and find an improvement in our capacity to model the experimental particle and energy sinks in the SOL.Description
