High-throughput full-f gyrokinetics of the tokamak boundary
A. C. D. Hoffmann, M. Francisquez, T. N. Bernard +2
Full-f global gyrokinetic simulations of the plasma boundary have until now required heroic computational efforts and case-by-case expert intervention, precluding systematic parame…
Towards fully predictive gyrokinetic full-f simulations: validation and triangularity studies in TCV
A. C. D. Hoffmann, T. N. Bernard, M. Francisquez +6
Designing economical magnetic confinement fusion power plants motivates computational tools that can estimate plasma behavior from engineering parameters without direct reliance on…
The hot-electron closure of the moment-based gyrokinetic plasma model
A. C. D. Hoffmann, P. Giroud-Garampon, P. Ricci
We derive the hot-electron-limit (HEL) closure for the moment hierarchy used to solve the gyrokinetic equations, known as the gyromoment (GM) approach. By expanding the gyroaveragi…
Investigation of triangularity effects on tokamak edge turbulence through multi-fidelity gyrokinetic simulations
A. C. D. Hoffmann, P. Ricci
This paper uses the gyro-moment (GM) approach as a multi-fidelity tool to explore the effect of triangularity on tokamak edge turbulence. Considering experimental data from an L-mo…
