Energy confinement scaling in Tokamaks:some implications of recent experiments with Ohmic and strong auxiliary heating

Abstract

Recent results from confinement scaling experiments on tokamaks with Ohmic and strongauxiliary heating are reviewed. An attempt is made to draw these results together into a"low-density" ohmic confinement scaling law, and a scaling law for confinement withauxiliary heating. The auxiliary heating confinement law may also serve to explain thesaturation in TE vs. n̄e observed in some ohmic heating density scaling experiments.
