Turbulent heating of a 10 cm radius plasma in a tokamak configuration with densities up to 10/sup 13//cm/sup 3/ produces a strong skin effect. Although the applied electric field at the outside of the column reaches 100 V/cm and the electron drift velocity exceeds the thermal velocity, penetration is slight at these densities during the 1 ..mu..sec pulse. The energy dissipated in the skin during the pulse can reach 5 mJ/cm/sup 3/, the equivalent of 30 keV per electron there, but losses associated with the turbulence are substantial. Average electron energies from the heating larger than 2 keV in the skin and 500 eV overall have not been found.
