Microtearing Thresholds and Second-Stable Ballooning in the DIII-D Pedestal: Reduced Modeling and Core-Edge Implications
David R. Hatch, Leonhard A. Leppin, Mike T. Kotschenreuther +4
Global and local linear gyrokinetic simulations of 42 pedestal equilibria from three DIII-D discharges are used to investigate pedestal stability and its impact on pedestal structu…

Modeling Temperature Profiles in the Pedestal of NSTX with Reduced Models
P. -Y. Li, D. R. Hatch, L. A. Leppin +5
This paper describes new modeling capabilities for predicting H-mode pedestal profiles in spherical tokamaks. Temperature profiles for NSTX discharges 132543 and 132588 are modeled…

The JET hybrid H-mode scenario from a pedestal turbulence perspective
L. A. Leppin, T. Görler, L. Frassinetti +4
Turbulent transport is a decisive factor in determining the pedestal structure of H-modes. Here, we present the first comprehensive characterization of gyrokinetic turbulent transp…
