Initial operation of the tokamak fusion test reactor has concentrated upon confinement studies of Ohmically heated hydrogen and deuterium plasmas. Total energy confinement times (E) are 0.1-0.2 s for a line-average density range (n»e) of (1-2.5)×1019 m-3 with electron temperatures of Te(0)1.2-2.2 keV, ion temperatures of Ti(0)0.9-1.5 keV, and Zeff3. A comparison of Princeton large torus, poloidal divertor experiment, and tokamak fusion test reactor plasma confinement supports a dimension-cubed scaling law.
