The confinement of plasma produced by electron cyclotron heating in the ELMO Bumpy Torus (EBT) has been studied in the regime stabilized by the diamagnetism of annular, energetic electrons. The electron density (n/sub e/ = 1-2 x 10/sup 12/ cm/sup -3/) and temperature (150 less than or equal to T/sub e/ less than or equal to 600 eV) and ion temperature 30 less than or equal to T/sub i/ less than or equal to 150 eV) have been measured over a range of operating conditions. Measurement of the direction of the electric field (inward pointing) inside the toroidally confined plasma has led to improved neoclassical theoretical models of plasma transport which describe reasonably well the observed parameter dependences over a wider range of collisionality than reported previously.
