Experimental Evidence for Increased Particle Fluxes Due to a Change in Transport at the Separatrix near Density Limits on Alcator C-Mod
M. A. Miller, J. W. Hughes, T. Eich +5
Experimental inferences of cross-field particle flux at the separatrix, , show rapid growth near H-mode and L-mode density limits at high magnetic field on…
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…
Power handling in a highly-radiative negative triangularity pilot plant
M. A. Miller, D. Arnold, M. Wigram +7
This work explores power handling solutions for high-field, highly-radiative negative triangularity (NT) reactors based around the MANTA concept \cite{rutherford_manta_2024}. The d…
Particle control via cryopumping and its impact on the edge plasma profiles of Alcator C-Mod
M. A. Miller, J. W. Hughes, S. Mordijck +4
At the high proposed for high-field fusion reactors, it is uncertain whether ionization, as opposed to plasma transport, will be most influential in determining at…
MANTA: A Negative-Triangularity NASEM-Compliant Fusion Pilot Plant
MANTA Collaboration, G. Rutherford, H. S. Wilson +38
The MANTA (Modular Adjustable Negative Triangularity ARC-class) design study investigated how negative-triangularity (NT) may be leveraged in a compact, fusion pilot plant (FPP) to…
