First step toward multi machine ELM energy scalings and extrapolations to SPARC and ITER
R. Perillo, A. Redl, T. Eich +14
It is shown that the ELM energy loss normalized by the plasma stored energy (ΔEELM/Wplasma) for high-density small/QCE ELM regimes scales inversely with the separatrix turbulence p…
Improved n=1 Empirical Error Field Penetration Threshold Scaling with Ohmic and L-Mode Conventional Tokamak Plasma Discharges
E. M. Bursch, J. K. Park, N. C. Logan +12
This paper presents an updated n=1 error field penetration threshold scaling, which increases fit quality compared to previous error field scaling laws, is produced from an expande…
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…
A predictive formula for the H-mode electron separatrix density: Bridging regression and physics-based models across C-Mod, AUG and JET tokamaks
D. Silvagni, O. Grover, A. Stagni +27
The electron density at the separatrix () plays a central role in balancing energy confinement, detachment achievement, and ELM suppression in tokamaks, thereby…
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. T…
Reconstructions of electron-temperature profiles from EUROfusion Pedestal Database using turbulence models and machine learning
L. -P. Turica, A. R. Field, L. Frassinetti +3
This study uses plasma-profile data from the EUROfusion pedestal database, focusing on the electron-temperature and electron-density profiles in the edge region of H-mode ELMy JET…
