Peaking and hollowness of low-Z impurity profiles: an interplay between ITG and TEM induced turbulent transport

open access: yesNuclear Fusion, 2023
The transport of low-Z impurities in fusion plasmas is dominated, in many regimes of interest, by ion temperature gradient (ITG) and trapped electron mode (TEM) turbulence. We use a statistical test-particle approach to analyze the effects of these drift
