Kinetic description of ponderomotive effects in a plasma
The kinetic treatment of the pondermotive force concept is found from nonresonant quasilinear theory for waves with spatially dependent amplitude. In general, the ponderomotive effect appears as a velocity space diffusion term, not as just a force. For an unmagnetized plasma, the quasilinear equations are solved directly, and the correct density modification exhibited explicitly. Examples are considered for both a homogeneous and an inhomogeneous magnetic field, and aspects of rf end plugging are discussed.
