Impurity Asymmetries and Radial Transport Produced by Asymmetric Impurity Sources

摘要

A fluid theory is presented for the effects of poloidal asymmetries in impurity sources upon the poloidal asymmetry over the flux surface of the impurity density and upon radial impurity transport in tokamak plasmas. Poloidal locations of limiters or divertors which would minimize inward impurity transport are identified. (ERA citation 11:035228)
