Vacuum ultraviolet spectroscopic study of plasma impurities in the Tokapole II poloidal divertor experiment
Description: The main diagnostics were two vacuum ultraviolet spectrometers, which were used to identify impurities, observe impurity behavior, and measure the line radiated power. Impurity concentrations and the effects of impurities on gross plasma characteristics were determined with an impurity doping technique. The electron temperature was estimated by a time dependent coronal model describing the time history of the oxygen ions, and the ion temperature was obtaind from Doppler broadening measurements. Energy loss processes were studied with a power balance analysis.
