Impurity transport and its modification by MHD in tokamak plasmas, with application to tungsten in WEST

Abstract

Neoclassical impurity transport & poloidal asymmetry -Can be determined analytically in a self-consistent way -Natural asymmetry (no torque) has already a large impact A magnetic island suppresses thermal screening above a critical size -Verified numerically on a typical WEST plasma equilibrium -When impurity transport is predominantly turbulent (as on WEST) Poloidal asymmetry remains essentially neoclassical
