Transport in a steady-state rigid-rotor FRC

Summary form only given, as follows. A steady-state field-reversed-configuration was generated by the rotating magnetic field (RMF) technique in a straight section of Racetrack. The plasma equilibrium is of the rigid rotor type. The effects of RMF current drive on particle, energy, and momentum transport were studied. The total power input by the moving magnetic field is substantially larger than the power dissipated by the diamagnetic current alone. The surplus power provides for ionization and heating. Radial fluid velocity is significant, and about 30% of the diamagnetic current is driven by the radial plasma motion. Temperature profiles are flat, and most of the energy is being convected by the particles. Plasma decay is approximately self-similar both spatially and temporally; the most important time- and space-dependent parameter is found to be the radius of the magnetic axis. The effect of equilibrium length on transport times is being investigated
