Theory of two-fluid equilibrium of an axially symmetric plasma
The two-fluid equilibrium of an axially symmetric plasma may be determined by a formula which is particularly useful for the case when a local charge separation causes a deviation of the equipotential surface from the magnetic surface. The inertia force due to plasma motion is considered in the form of a modified electrostatic potential (caused by centrifugal force) and a modified magnetic field (caused by Coriolis force). A set of partial differential equations which determine the modified flux functions and the self-consistent electric and magnetic fields are derived. The poloidal drift flux on the modified magnetic surface and the density and temperature in the absence of both the electrostatic potential and the plasma flow are assumed. The result is formulated as a variation principle which contains no constraints and hence is useful for numerical and perturbational analysis.
