Particle-in-cell simulations of expanding high energy density plasmas with laser ray tracing
K. V. Lezhnin, S. R. Totorica, A. S. Hyder +5
The design and analysis of high energy density (HED) laser experiments typically rely on radiation hydrodynamics simulations. However, some laser-plasma interaction regimes are not…

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-Limited Pedestals in Spherical Tokamak Plasmas
J. F. Parisi, W. Guttenfelder, A. O. Nelson +12
A theoretical model is presented that for the first time matches experimental measurements of the pedestal width-height Diallo scaling in the low-aspect-ratio high- tokamak NSTX…
