EFFECTS OF RADIAL FLOW ON CURRENT DRIVE IN A FIELD-REVERSED CONFIGURATION BY A ROTATING MAGNETIC-FIELD

The equilibrium of a field reversed configuration (FRC) with a rotatin g magnetic field (RMF) applied externally for maintaining steady state is studied theoretically. The momentum balance equations of ions and electrons as well as the mass balance equations have been solved analy tically and a solution of a steady equilibrium of the FRC with the RMF , in which the ions and electrons rotate at different velocities, has been found. It has been revealed that the particle source and the radi al flow neglected in previous studies plays an important role in the e quilibrium.
