Tokamak energy confinement scaling in TFTR L mode andsupershot regimes is discussed. The main result is that TFTR L mode plasmasfit the supershot scaling law for energy confinement. In both regimes, plasmatransport coefficients increased with increased edge deuterium influx. Thecommon L mode confinement scaling law on TFTR is also inversely proportionalto the volume of wall material that is heated to a high temperature, possiblythe temperature at which the deuterium sorbed in the material becomes detrappedand highly mobile. The deuterium influx is increased by: (a) increased beampower due to a deeper heated depth in the edge components and (b) decreasedplasma current due to an increased wetted area as governed by the empiricallyobserved dependence of the SOL width upon plasma current.
