It is shown that the energy-transfer efficiencies of opening switch and closing switch Ohmic heating transformers differ significantly, and that the efficiency of an opening switch transformer can be optimized by using an iron core with a substantial air gap (gap comparable to the plasma minor radius). A demonstration on the Caltech Encore gapped iron core tokamak is cited.
