Measurements and neoclassical modeling of deuterium and impurity toroidal rotation and temperature profiles in the H-mode pedestal and steep gradient region*

Advances in main-ion charge exchange recombination spectroscopy (MICER) have enabled first measurements of the simultaneous main-ion (D+) and impurity ion (C6+) properties from the core to the scrape off layer in a tokamak. This capability has revealed clear differences between the deuterium and impurity temperature and toroidal rotation near the separatrix. These differences are compared with neoclassical models including analytic (Kim-Diamond-Groebner), local drift-kinetic (NEO), and global drift-kinetic including the effect of neutrals (XGC0). A low temperature H-mode is studied where kinetic and non-local effects are expected to be small. Initial analysis shows the strong effect that an edge neutral population can have in reducing both the main ion toroidal rotation and temperatures, and their importance in bringing predictions into better agreement with experimental measurements.
