Global effects on neoclassical transport in the pedestal with impurities
We present a numerical study of collisional transport in a tokamak pedestal in the presence of non-trace impurities, using the radially global δf neoclassical solver Perfect [M.Landreman et al. 2014 Plasma Phys.Control.Fusion 56 045005].It is known that in a tokamak core with non-trace impurities present the radial impurity flux opposes …
