PQLS: A Quasilinear Gyrokinetic Transport Solver with a Bayesian Saturation-Rule Closure
F. Wilms, A. Agrawal, J. J. Freigang +3
Quasilinear models make gyrokinetic turbulent-transport predictions sufficiently fast for integrated modelling, but their predictive capability is limited by two factors: the physi…
Multiscale turbulence in stellarators
G. Merlo, A. Bañón Navarro, T. Görler +2
We present the first gyrokinetic simulations of multiscale turbulence in a stellarator, using the magnetic geometry of Wendelstein 7-X (W7-X) and experimentally relevant parameters…
Validation of a Comprehensive First-Principles-Based Framework for Predicting the Performance of Future Stellarators
D. L. C. Agapito Fernando, A. Bañón Navarro, D. Carralero +20
This paper presents the validation of the framework for recovering both the steady-state plasma profiles in the considered radial domain and selected t…
Global gyrokinetic analysis of Wendelstein 7-X discharge: unveiling the importance of trapped-electron-mode and electron-temperature-gradient turbulence
Felix Wilms, Alejandro Bañón Navarro, Thomas Windisch +8
We present the first nonlinear, gyrokinetic, radially global simulation of a discharge of the Wendelstein 7-X-like stellarator (W7-X), including kinetic electrons, an equilibrium r…
Assessing global ion thermal confinement in critical-gradient-optimized stellarators
A. Bañón Navarro, G. T. Roberg-Clark, G. G. Plunk +4
We investigate the confinement properties of two recently devised quasi-helically symmetric stellarator configurations, HSK and QSTK. Both have been optimized for large critical gr…
Instabilities and turbulence in stellarators from the perspective of global codes
E. Sánchez, A. Bañón Navarro, F. Wilms +3
In this work, a comparison of the global gyrokinetic codes EUTERPE and GENE-3D in stellarator configurations of LHD and W7-X is carried out. In linear simulations with adiabatic el…
First-principles based plasma profile predictions for optimized stellarators
A. Bañón Navarro, A. Di Siena, J. L. Velasco +6
In the present Letter, first-of-its-kind computer simulations predicting plasma profiles for modern optimized stellarators -- while self-consistently retaining neoclassical transpo…
