Effect of insulator end cap thickness on time-dependent Hartmann flow in a rotating mirror
Rahul Gaur, Ian G. Abel, Bindesh Tripathi +1
We present a framework for analyzing plasma flow in a rotating mirror. By making a series of physical assumptions, we reduce the magnetohydrodynamic (MHD) equations in a three-dime…

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^{…

Kinetic-Ballooning-Bifurcation in Tokamak Pedestals Across Shaping and Aspect-Ratio
J. F. Parisi, A. O. Nelson, R. Gaur +16
We use a new gyrokinetic threshold model to predict a bifurcation in tokamak pedestal width-height scalings that depends strongly on plasma shaping and aspect-ratio. The bifurcatio…
