The effect of separatrix density and PFC material on H-mode confinement in the ITPA global H-mode database
M. Kotschenreuther, X. Liu, D. R. Hatch +1
Recent data, added to the ITPA global H-mode database [1] for ASDEX-U [2] and JET-ILW, reveals that the separatrix density has a correlation with the H20 factor (Confinem…
Prospects of negative triangularity tokamak for advanced steady-state confinement of fusion plasmas
Linjin Zheng, M. T. Kotschenreuther, F. L. Waelbroeck +4
The steady-state confinement, beta limit, and divertor heat load are among the most concerned issues for toroidal confinement of fusion plasmas. In this work, we show that the nega…
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…
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…
