Stability and Transport of Gyrokinetic Critical Pedestals
J. F. Parisi, A. O. Nelson, W. Guttenfelder +11
A gyrokinetic threshold model for pedestal width-height scaling prediction is applied to multiple devices and to a shaping and aspect-ratio scan giving $Δ_{\mathrm{ped}} = 0.92 A^{…
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…
Microtearding mode study in NSTX using machine learning enhanced reduced model
Max T. Curie, Joel Larakers, Jason Parisi +18
This article presents a survey of NSTX cases to study the microtearing mode (MTM) stabilities using the newly developed global reduced model for Slab-Like Microtearing modes (SLiM)…
Gyrokinetic Simulations Compared with Magnetic Fluctuations Diagnosed with a Faraday-Effect Radial Interferometer-Polarimeter in the DIII-D pedestal
M. T. Curie, D. R. Hatch, M. Halfmoon +6
Experimental data on electromagnetic fluctuations in DIII-D, made available by the Faraday-effect Radial Interferometer-Polarimeter (RIP) diagnostic, is examined in comparison with…
