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

Recent results from confinement scaling experiments on tokamaks with Ohmic and strong auxiliary 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 with auxiliary heating. The auxiliary heating confinement law may also serve to explain the saturation in TE vs. e observed in some ohmic heating density scaling experiments.
