KINETIC GUIDING CENTER EQUATIONS FOR THE THEORY OF DRIFT INSTABILITIES AND ANOMALOUS TRANSPORT
Littlejohn's guiding-center mechanics, with the polarization drift included, is rederived from a Lagrangian. The respective collisionless kinetic guiding-center theory is then established. Even though single-guiding-center energy is exactly conserved here in time-independent fields, the total energy of the resulting guiding-center plasma and its self-consistent fields is only approximately conserved (to leading order in epsilon = taug/L). This is unlike in the case without polarization drift, where exact conservation of total energy obtains. Nevertheless, the present formalism seems to be important for the theory of drift waves and anomalous transport.
