A zero-dimensional transport model for field-reversed configurations

Abstract

A zero-dimensional theoretical model is developed to study energy, particle, and magnetic flux confinement during the equilibrium phase in field-reversed configurations. The plasma is heated by adiabatic compression from the external magnetic field and by ohmic dissipation. Energy is lost from lower-hybrid-drift induced particle transport, classical and anomalous thermal conduction, and impurity line radiation. As an example, the model is used to analyze data measured in the FRX-C experiment.
