BOUNCE RESONANCE HEATING AND TRANSPORT IN A MAGNETIC-MIRROR

Bounce resonance heating and associated radial transport in a magnetic mirror are studied. A general expression for the absorbed power and radial particle flux due to bounce resonance is obtained by use of a gyrokinetic equation with the eikonal representation for waves. It is shown that the power absorption yields the outward (inward) particle flux with positive (negative) azimuthal mode number of RF wave fields, and that the power emission, i.e., instabilities, yields the reverse particle flux with the same mode number for the ion. The particle flux for the electron is opposite that for the ion.
