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…
Transport Barriers in Magnetized Plasmas -- General Theory with Dynamical Constraints
Mike Kotschenreuther, Xing Liu, Swadesh M. Mahajan +2
A fundamental dynamical constraint -- that fluctuation induced charge-weighted particle flux must vanish -- can prevent instabilities from accessing the free energy in the strong g…
The free energy balance equation applied to gyrokinetic instabilities, the effect of the charge flux constraint, and application to simplified kinetic models
M. Kotschenreuther, X. Liu, S. M. Mahajan +1
The free energy balance equation for gyrokinetic fluctuations is derived and applied to instabilities. An additional term due to electromagnetic sources is included. This can provi…
Modeling electron temperature profiles in the pedestal with simple formulas for ETG transport
D. R. Hatch, M. T. Kotschenreuther, P. -Y. Li +4
This paper reports on the refinement (building on Ref.~\cite{hatch_22}) and application of simple formulas for electron heat transport from electron temperature gradient (ETG) driv…
Direct Gyrokinetic Comparison of Pedestal Transport in JET with Carbon and ITER-Like Walls
D. R. Hatch, M. Kotschenreuther, S. M. Mahajan +8
This paper compares the gyrokinetic instabilities and transport in two representative JET pedestals, one (pulse 78697) from the JET configuration with a carbon wall (C) and another…
Flow Shear Suppression of Pedestal Turbulence--A First Principles Theoretical Framework
D. R. Hatch, R. D. Hazeltine, M. K. Kotschenreuther +1
A combined analytic and computational gyrokinetic approach is developed to address the question of the scaling of pedestal turbulent transport with arbitrary levels of …
