Analytic and two-dimensional computational solutions for the plasma parameters near a toroidally synnetric limiter are illustrated for the projected parameters of a Tokamak Fusion Core Experiment {TFCX). The temperature near the limiter plate is belo* 20 eV, except when the density 10 cm inside the limiter contact is 8 x 10' 3 cm~3 or less and the thermal diffusivity in the edge region is 2 x 10*cin 2 /s or less. Extrapolation of recent experimental data suggests that neither of these conditions is likely to be met near ignition in TFCX, 30 a low plasma temperature near the limiter should be considered a likely possibility.
