Combining linear gyrokinetics with self-consistent pedestal equilibrium variation, kinetic-ballooning, rather than ideal-ballooning plasma instability, is shown to limit achievable confinement in spherical tokamak pedestals. Simulations are used to find the novel Gyrokinetic Critical Pedestal constraint, which determines the steepest pressure profile a pedestal can sustain subject to gyrokinetic instability. Gyrokinetic width-height scaling expressions for NSTX pedestals with varying density and temperature profiles are obtained. These scalings for STs depart significantly from that of conventional aspect ratio tokamaks."},"author":{"citation:authorName":"Parisi, J.F.; Guttenfelder, W.; Nelson, A.O.; Gaur, R.; Kleiner, A.; Lampert, M.; Avdeeva, G.; Berkery, J.W.; Clauser, C.; Curie, M.; Diallo, A.; Dorland, W.; Kaye, S.M.; Mcclenaghan, J.; Parra, F.I."},"citation:datasetContact":{"citation:datasetContactEmail":"jparisi@pppl.gov"},"title":"Kinetic-ballooning-limited pedestals in spherical tokamak plasmas","subject":"Physics","citation:notesText":"<a href=\"http://library.psfc.mit.edu/catalog/reports/2020/24ja/24ja126/abstract.php\">PSFC REPORT PSFC/JA-24-126</a><br /><br />This work was supported by the U.S. Department of Energy under Contract Numbers DE-AC02-09CH11466, DE-SC0022270, DE-SC0022272, and the Department of Energy Early Career Research Program.
