In the ELMO Bumpy Torus (EBT) a macroscopically stable regime of operation is expected theoretically and observed experimentally. The power level for microwave bulk heating has recently been doubled to 60 kW, and the resulting plasma parameters scaled encouragingly with this increase in microwave power (e.g., T/sub i/ greater than or equal to 130 eV). The plasma beta for the higher microwave power is approximately 1%; this is still well below the theoretical macroscopic magnetohydrodynamic (MHD) instability limit: a plasma beta comparable to the beta of the hot electron annuli can be stably confined provided a minimum exists in the magnetic field. A radially resolved fluid transport code, based upon refined neoclassical coefficients, yields results which are in reasonable agreement with earlier and recent experimental observations.
