Abstract

- Due to their high cross field mobility, neutral atoms can have a strong effect on transporteven at the low relative densities found inside the separatrix. We use a charge-exchange dominatedmodel for the neutrals, coupled to neoclassical ions, to calculate momentum transport when it isdominated by the neutrals. We can then calculate self-consistently the radial electric field and predictthe intrinsic rotation in a torque-free plasma. Using a numerical solver for the ion distribution toallow arbitrary collisionality, we investigate the effects of inverse aspect ratio and elongation on plasmarotation. We also calculate the rotation of a trace carbon impurity, to facilitate future comparison toexperiments using charge exchange recombination spectroscopy diagnostics.
