Interpretation of momentum confinement in recent JET (Joint European Torus) and TFTR (Tokamak Fusion Test Reactor) experiments
Unbalanced neutral beam injection, used to heat tokamak plasmas, causes the plasma to rotate. It is well documented that the observed momentum confinement time cannot be explained by the existing neoclassical theory of perpendicular viscous momentum transfer. Analysis of Impurity Study Experiment-B, Poloidal Divertor Experiment, and Princeton Large Torus PDX, and data based on the more recent gyroviscous theory of momentum confinement, however, showed good agreement between theory and experiment. In this paper, results from recent Joint European Torus (JET) and Tokamak Fusion Test Reactor (TFTR) experiments in which the various plasma parameters were measured with a good degree of accuracy are presented and shown to be in agreement with the prediction of the gyroviscous theory. 6 refs., 2 figs.
