Characterization of reduced-order turbulence models in the L-mode pedestal-forming region in JET
G. Snoep, C. Bourdelle, J. Citrin +7
Linear instability characterization of seven JET discharges just prior to the L-H transition is performed at with the gyrokinetic GENE code. Th…
Integrated modelling and multiscale gyrokinetic validation study of ETG turbulence in a JET hybrid H-mode scenario
J Citrin, S Maeyama, C Angioni +11
Previous studies with first-principle-based integrated modelling suggested that ETG turbulence may lead to an anti-GyroBohm isotope scaling in JET high-performance hybrid H-mode sc…
The Problem of Marginality in Model Reductions of Turbulence
C. Gillot, G. Dif-Pradalier, Y. Sarazin +8
Reduced quasilinear (QL) and nonlinear (gradient-driven) models with scale separations, commonly used to interpret experiments and to forecast turbulent transport levels in magneti…
Application of Gaussian process regression to plasma turbulent transport model validation via integrated modelling
Aaron Ho, Jonathan Citrin, Fulvio Auriemma +7
This paper outlines an approach towards improved rigour in tokamak turbulence transport model validation within integrated modelling. Gaussian process regression (GPR) techniques w…
Neural network surrogate of QuaLiKiz using JET experimental data to populate training space
Aaron Ho, Jonathan Citrin, Clarisse Bourdelle +5
Within integrated tokamak plasma modelling, turbulent transport codes are typically the computational bottleneck limiting their routine use outside of post-discharge analysis. Neur…
Quasilinear gyrokinetic theory: A derivation of QuaLiKiz
Cole Darin Stephens, Xavier Garbet, Jonathan Citrin +3
In order to predict and analyze turbulent transport in tokamaks, it is important to model transport that arises from microinstabilities. For this task, quasilinear codes have been…
