Abstract
In this paper, a new spatially resolving X-ray crystal spectrometer (XCS) capable of measuring continuous spatial profiles of high resolution spectra (lambda/dlambda > 6000) of He-like and H-like Ar Kalpha lines has been installed on the Alcator C-Mod tokamak. The spectrometer has an improved measurements on ion temperature (Ti), intrinsic rotation-velocity profiles (vphi) with excellent spatial (~1 cm) and temporal resolution, and on the atomic physics of highly charged ions.The data analysis techniques, (Ti) and (vphi) profile results, analysis of background resulting from fusion neutrons, and predictions of performance on the international tokamak ITER and other tokamaks is presented.
