Greene, J M; Winsor, N K

For a resistive plasma of stellarator or low-temperature tokamak type, the quasi-stationary equilibrium is in rotation at the reduced sound speed B/sub theta/v/sub th//B/sub z/, and has a slow (acoustic branch) shock fixed in space. Dissipation in the shock can increase plasma loss by an order of magnitude over the Pfirsch-Schlueter rate. For a very weak shock, the loss rate scales with the resistivity as eta/sup 4/3/; for a stronger (but still weak) shock, it scales as eta/sup 3/2/. On the diffusion time scale, flow along the lines of force must develop. 19 refs.
