摘要：

Radial transport induced by rotating RF fields in a magnetic mirror is studied. The RF frequency used is in the ion cyclotron range of frequency and is comparable to the electron bounce frequency. The radial particle fluxes for ions and electrons are obtained by use of the gyrokinetic equation. With a positive azimuthal mode number of the RF field, the radial particle flux is outward for Maxwellian ions and inward for Maxwellian electrons. This shows that the intrinsic ambipolarity is broken in this RF-induced transport. The present analyses can be applied to the thermal-barrier pumping of a tandem mirror.
