Description: In present experiments, FRC's (field-reversed configurations) are generated on dynamic time scales using pulsed high-power theta-pinch technology, which does not easily extrapolate to reactor-size devices. The attractiveness of FRC reactor scenarios would be enhanced by the development of quasi-static (i.e. formation time >> Alfven time) formation techniques requiring moderate power levels. In this report the quasi-static formation of FRC plasmas is analytically investigated. The set of equations which yield the time evolution of the ohmically-heated-plasa parameters, under the constraints of radial equilibrium and plasma energy losses, are presented. Subject to the simplifying assumptions used in the model, this equation set is completely general and would apply to any ohmically-heated FRC. A sample calculation is presented in which the FRC azimuthal current, I/sub theta/, is generted by the rotating-magnetic-field (RMF) technique.
