NIMROD-to-IMAS workflow for extended-magnetohydrodynamic data with reusable datasets and implications for IMAS schema development
Alexei Y. Pankin, Fatima Ebrahimi, Qian Gong +5
Extended magnetohydrodynamic (MHD) simulations of tokamak plasmas regularly produce outputs in multi-dimensional, multiple-field formats; these code-specific formats make it diffic…
Prediction of ELM-free Operation in Spherical Tokamaks With High Plasma Squareness
J. F. Parisi, J. W. Berkery, K. Imada +5
We predict that high plasma squareness in spherical tokamaks (STs) could result in edge-localized-mode (ELM)-free H-mode. The effect of squareness on gyrokinetic and peeling-balloo…
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…
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…
