Validation of edge turbulence codes against the TCV-X21 diverted L-mode reference case
D. S. Oliveira, T. Body, D. Galassi +27
Self-consistent full-size turbulent-transport simulations of the divertor and SOL of existing tokamaks have recently become feasible. This enables the direct comparison of turbulen…
The power exhaust constrained SPARC separatrix operational space
B. Lomanowski, T. Eich, J. D. Lore +3
In this work we extrapolate the separatrix operational space (SepOS) projections to SPARC and introduce detachment access criteria, thus formulating the combined power exhaust cons…
Reduced model for H-mode sustainment in unfavorable drift configuration in ASDEX Upgrade
O. Grover, T. Eich, P. Manz +6
A recently developed reduced model of H-mode sustainment based on interchange-drift-Alfvén turbulence description in the vicinity of the separatrix matching experimental observati…
Accelerating integrated modeling with surrogate-based optimization: the MAESTRO workflow
P. Rodriguez-Fernandez, N. T. Howard, J. Hall +14
This paper introduces the MAESTRO workflow, that enables the coupling of the PORTALS framework [P. Rodriguez-Fernandez et al, Nucl. Fusion 2024] with external solvers for the plasm…
Impact of model uncertainty on SPARC operating scenario predictions with empirical modeling
A. Saltzman, P. Rodriguez-Fernandez, T. Body +2
Understanding and accounting for uncertainty helps to ensure next-step tokamaks such as SPARC will robustly achieve their goals. While traditional Plasma OPerating CONtour (POPCON)…
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…
