Machine learning methods for modelling local, linear gyrokinetic simulations of MAST-U pedestal turbulence
Anna Niemelä, Daniel Jordan, Aaro Järvinen +8
Gyrokinetic (GK) stability strongly influences the performance of high-confinement-mode pedestals in spherical tokamak plasmas. High-fidelity gyrokinetic codes such as GENE can mod…
Integrating Gyrokinetic Flux Predictions with Ideal MHD Stability Boundaries
J. McClenaghan, K. E. Thome, T. F. Neiser +5
Accurate prediction of pedestal height and width in tokamaks remains a critical issue as it strongly influences the predicted plasma performance of all future reactors. We present…
The physics of ELM-free regimes in EUROfusion tokamaks
M. G. Dunne, M. Faitsch, O. Sauter +25
The development of operational scenarios without large Type-I ELMs is of utmost importance for the stable operation and longevity of future tokamaks. The EUROfusion tokamak exploit…
Empirical impact of near-separatrix plasma and neutral transport on the pedestal in the transition between EDA and ELMy H-modes on Alcator C-Mod
M. A. Miller, J. W. Hughes, S. Saarelma +16
The transition between the ELMy H-mode and the EDA H-mode is studied on Alcator C-Mod using an experimental database and predictive pedestal models. High-resolution Thomson scatter…
EuroPED-NN: Uncertainty aware surrogate model
A. Panera Alvarez, A. Ho, A. Jarvinen +4
This work successfully generates an uncertainty-aware surrogate model of the EuroPED plasma pedestal model using the Bayesian neural network with noise contrastive prior (BNN-NCP)…
H-mode inhibition in negative triangularity tokamak reactor plasmas
A. O. Nelson, C. Paz-Soldan, S. Saarelma
Instability to high toroidal mode number () ballooning modes has been proposed as the primary gradient-limiting mechanism for tokamak equilibria with negative triangularity (…
