Abstract

The parallel and poloidal rotation speeds are calculated on the basis of the ambipolarity constraint and the parallel momentum equation of the revisited neoclassical theory. The temperature is estimated by means of the power balance. Source terms account for the momentum deposition by neutral beam injection, the eddy currents in the wall, pressure anisotropization and the j×B force density. The main results are: (1) At a DED (TEXTOR) frequency of 10 kHz a toroidal velocity gradient of 1.2 10⁶ 1/sec may be achieved and thus an ITB be generated. (2) The (subneoclassical) pressure pedestal in a (rotating) medium size H - mode plasma may be stabilized against the ballooning-peeling instability by ergodization.
