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)…
SOLPS-ITER simulation of an X-point radiator in TCV
G. Sun, O. Pan, M. Bernert +7
SOLPS-ITER simulation is performed to reproduce the X-point radiator recently observed in nitrogen-seeded TCV experiments, which is a scenario that may be favorable to solve the po…
On learning latent dynamics of the AUG plasma state
A. Kit, A. E. Järvinen, Y. R. J. Poels +5
In this work, we demonstrate the utility of state representation learning applied to modeling the time evolution of electron density and temperature profiles at ASDEX-Upgrade (AUG)…
Fast Dynamic 1D Simulation of Divertor Plasmas with Neural PDE Surrogates
Yoeri Poels, Gijs Derks, Egbert Westerhof +3
Managing divertor plasmas is crucial for operating reactor scale tokamak devices due to heat and particle flux constraints on the divertor target. Simulation is an important tool t…
Deep or Not Deep: Supervised Learning Approaches to Modeling the Pedestal Density
Adam Kit, Aaro Jaervinen, Lorenzo Frassinetti +2
Pedestal is the key to conventional high performance plasma scenarios in tokamaks. However, high fidelity simulations of pedestal plasmas are extremely challenging due to the multi…
Developing Deep Learning Algorithms for Inferring Upstream Separatrix Density at JET
A. Kit, A. Jaervinen, S. Wiesen +2
Predictive and real-time inference capability for the upstream separatrix electron density, , is essential for design and control of core-edge integrated plasma sc…
Impact of nitrogen seeding on confinement and power load control of a high-triangularity JET ELMy H-mode plasma with a metal wall
C Giroud, G P Maddison, S Jachmich +39
This paper reports the impact on confinement and power load of the high-shape 2.5MA ELMy H-mode scenario at JET of a change from an all carbon plasma facing components to an all me…
