Abstract

Particle and energy conservation relations appropriate to drift and MHD ordering are derived and simplified in the MHD case by exploiting an invariant of guiding-centre motion existing when E. B = 0. An MHD perturbation calculation is made of the local average density and energy rates of change induced by a wave of general transverse-electric type in an inhomogeneous plasma. The resulting expressions, which incorporate the effect of equilibrium electric field on zeroth-order trajectories, are of striking simplicity. In the drift-ordered limit their divergence from other drift results is discussed; particle pump-out in the given heating fields is seen to be much smaller than found previously.
