Disentangling Core and Edge Mechanisms of the Density Limit in DIII-D Negative Triangularity Plasmas
R. Hong, P. H. Diamond, O. Sauter +14
The density limit is investigated in the DIII-D negative triangularity (NT) plasmas which lack a standard H-mode edge. We find the limit may not be a singular disruptive boundary b…

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…
