Predicting Negative Triangularity Edge Confinement with a Neutral-Coupled Full-f Gyrokinetic Model

T. N. Bernard, A. C. D Hoffmann, M. Francisquez +5

Global full-f gyrokinetic simulations coupled to a reduced neutral-fluid model reproduce key DIII-D experimental trends and identify mechanisms underlying improved confinement in n…

High-throughput full-f gyrokinetics of the tokamak boundary

A. C. D. Hoffmann, M. Francisquez, T. N. Bernard +2

Full-f gyrokinetics of the tokamak boundary have so far been limited to individual, expert-curated cases. We report hundreds of concurrent and unsupervised simulations of the edge…

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…

Development of Advanced Linearized Gyrokinetic Collision Operators Using a Moment Approach

B. J. Frei, J. Ball, A. C. D. Hoffmann +3

The derivation and numerical implementation of a linearized version of the gyrokinetic (GK) Coulomb collision operator (Jorge R. et al., J. Plasma Phys. 85, 905850604 (2019)) and o…
