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…
Core-edge integrated modeling of ARC: on the effect of impurity transport and detachment conditions
Marco Muraca, Pablo Rodriguez-Fernandez, Nathaniel T. Howard +5
Integrated modeling of ARC H-modes has been conducted to assess the feasibility of high-performance scenarios compatible with divertor detachment. The analysis incorporates self-co…
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…
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…
Determination of confinement regime boundaries via separatrix parameters on Alcator C-Mod based on a model for interchange-drift-Alfvén turbulence
M. A. Miller, J. W. Hughes, T. Eich +13
The separatrix operational space (SepOS) model [Eich \& Manz, \emph{Nuclear Fusion} (2021)] is shown to predict the L-H transition, the L-mode density limit, and the ideal MHD ball…
Effect of triangularity on plasma turbulence and the SOL-width scaling in L-mode diverted tokamak configurations
Kyungtak Lim, Maurizio Giacomin, Paolo Ricci +5
The effect of triangularity on tokamak boundary plasma turbulence is investigated by using global, flux-driven, three-dimensional, two-fluid simulations. The simulations show that…
I-mode pedestal relaxation events in the Alcator C-Mod and ASDEX Upgrade tokamaks
D. Silvagni, J. L. Terry, W. McCarthy +13
In some conditions, I-mode plasmas can feature pedestal relaxation events (PREs) that transiently enhance the energy reaching the divertor target plates. To shed light into their a…
I-mode pedestal relaxation events at ASDEX Upgrade
D. Silvagni, T. Eich, T. Happel +16
The I-mode confinement regime can feature small edge temperature drops that can lead to an increase in the energy deposited onto the divertor targets. In this work, we show that th…
