Abstract The design of commercially feasible magnetic confinement fusion reactors strongly relies on the reduced turbulent transport in plasma edge during operation high mode (H-mode). We present first global turbulence simulations ASDEX Upgrade tokamak and scrape-off layer ITER baseline H-mode conditions. Reasonable agreement with experiment is obtained for outboard mid-plane measurements density, electron ion temperature, as well radial electric field. heat underpredicted by roughly 1/3....
Understanding and predicting turbulent transport in the edge scrape-off-layer (SOL) of magnetic confinement fusion devices is crucial for developing feasible power plants. In this work, we present latest improvements to gyrokinetic turbulence code GENE-X validate extended model against experimental results TCV tokamak (“TCV-X21”). features a full-f electromagnetic specifically targeted SOL simulations diverted geometries. can effect collisions using either basic Bhatnagar–Gross–Krook (BGK)...

The understanding and the predictive capability for turbulence in plasma edge scrape-off layer (SOL) are crucial development of magnetic confinement fusion reactors. To this end, we characterise turbulent transport across SOL diverted ASDEX Upgrade tokamak attached L-mode conditions by means validated, global simulations. collisionality is controlled divertor neutrals density, as their ionisation increases density decreases temperature. radial E×B particle heat transport, quantified...
