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 paper investigates how plasma and neutral transport near the separatrix influence the edge pedestal during the transition between ELMy and EDA H-modes on the Alcator C‑Mod toka…
Enhanced pedestal transport driven by edge collisionality on Alcator C-Mod and its role in regulating H-mode pedestal gradients
M. A. Miller, J. W. Hughes, A. M. Rosenthal +7
Experimental measurements of plasma and neutral profiles across the pedestal are used in conjunction with 2D edge modeling to examine pedestal stiffness in Alcator C-Mod H-mode pla…
The separatrix operational space of next-step fusion experiments: From ASDEX Upgrade data to SPARC scenarios
Thomas Eich, Thomas Body, Michael Faitsch +13
Fusion power plants require ELM-free, detached operation to prevent divertor damage and erosion. The separatrix operational space (SepOS) is proposed as a tool for identifying acce…
Kinetic-Ballooning-Bifurcation in Tokamak Pedestals Across Shaping and Aspect-Ratio
J. F. Parisi, A. O. Nelson, R. Gaur +16
We use a new gyrokinetic threshold model to predict a bifurcation in tokamak pedestal width-height scalings that depends strongly on plasma shaping and aspect-ratio. The bifurcatio…
