Abstract

Current drive using anisotropic synchrotron radiation in a tokamak device is considered. A relativistic formulation of the current drive efficiency which includes both momentum transfer and asymmetric resistivity is presented. The explicit computation of the current drive efficiency is performed for a Maxwellian plasma using Trubnikov's theory of radiation. The effect of the various synchrotron harmonics on the total generated current is examined and it is shown that most of the contribution comes from a few harmonics near n = omega/omega-"rm c" gg 1 for which the corresponding resonant velocities are in the same direction. The general properties of the synchrotron radiation and its capability to generate current in a reactor are also briefly discussed.
