Magnetic Propulsion of Intense Lithium Streams in a Tokamak Magnetic Field

摘要

The paper gives the theory of magnetic propulsion of liquid lithium streams and their stability in tokamaks. In the approximation of a thin flowing layer the MHD equations are reduced to one integro-differential equation which takes into account the propulsion effect, viscosity and the drag force due to magnetic pumping and other interactions with the magnetic field. A criterion is obtained for the stabilization of the 'sausage' instability of the streams by centrifugal force.
