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…
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…
Comparison of filament properties in real-size GBS simulations and experiments of TCV-X21
Y. Wang, C. Wüthrich, C. Theiler +7
A direct quantitative comparison of Scrape-Off Layer (SOL) filament properties from fluid turbulence simulations using the GBS code and from experiments on the TCV tokamak is perfo…
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…
Core performance predictions in projected SPARC first-campaign plasmas with nonlinear CGYRO
P. Rodriguez-Fernandez, N. T. Howard, A. Saltzman +7
This work characterizes the core transport physics of SPARC early-campaign plasmas using the PORTALS-CGYRO framework. Empirical modeling of SPARC plasmas with L-mode confinement in…
Validation of SOLPS-ITER Simulations against the TCV-X21 Reference Case
Y. Wang, C. Colandrea, D. S. Oliveira +7
This paper presents a quantitative validation of SOLPS-ITER simulations against the TCV-X21 reference case and provides insights into the neutral dynamics and ionization source dis…
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 observatio…
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…
Treatment of Advanced Divertor Configurations in the Flux-Coordinate Independent turbulence code GRILLIX
Thomas Body, Andreas Stegmeir, Wladimir Zholobenko +2
Advanced divertor configurations modify the magnetic geometry of the diverter to achieve a combination of strong magnetic flux expansion, increased connection length and higher div…
Global turbulence simulations of the tokamak edge region with GRILLIX
A. Stegmeir, A. Ross, T. Body +8
Turbulent dynamics in the scrape-off layer (SOL) of magnetic fusion devices is intermittent with large fluctuations in density and pressure. Therefore, a model is required that all…
