Tokamak devices

Abstract
This survey deals with research on plasma in toroidal systems with strong longitudinal fields (Tokamak devices). The author first of all considers the movement of single particles in these systems and then reviews the theoretical work on equilibrium, transport coefficients and plasma stability. The design of the various Tokamak devices is described, as are the methods of plasma diagnostics employed with them. The main experimental results are summarized and compared with theory. Possible methods of heating plasma are considered and the prospects of the Tokamak program discussed.
