The role of poloidal asymmetries in impurity transport
Paper in proceedings, 2011

If the density of the impurity ions is poloidally asymmetric then the zero-flux impurity density gradient (the peaking factor) can be reduced. The convective impurity flux can even change sign if the asymmetry is sufficiently large. This effect is most effective in low-shear plasmas with the impurity density peaking on the inboard side and may be a contributing factor to the observed outward convection of impurities in the presence of radio frequency (RF) heating.
