英文摘要The effect of the Coriolis force due to the impurity toroidal and poloidal rotation on the in-out impurity density asymmetry in a rotating tokamak plasma is investigated. The role of the Coriolis force is figured out explicitly in the toroidally rotating plasma frame. The in-out impurity density asynunetry can be induced by the Coriolis force with qv(theta)(,)(z)w(z) > 0, in this case, when moving along the magnetic field line from the outboard side to the inboard side in a magnetic flux surface, one sees a positive Coriolis force. The combined effects of the centrifugal force, the Coriolis force, the poloidal electric field and the ion-impurity friction force on the in-out impurity density asymmetry are discussed. The proposed theoretical model can be applied to improve the understanding of the in-out impurity density asymmetry observed in the tokamak experiments.
