UWFDM-1102 Energy and Particle Confinement Times for a Field-Reversed Configuration

The energy and particle lifetime scalings in a field-reversed configuration (FRC) are shown to depend on transport regimes and geometric parameters. The improved formulas have been compared with other empirical and theoretical scaling laws. The result is that confinement time dependence agrees with experimental measurements (for the present status of the experiments Ti ≤ 1 keV and s > 1) of energy and particle loss both in magnitude and scaling, becoming smaller as the collision frequency decreases. The importance of the anomalous transport theory for a FRC is discussed.
