This thesis develops the foundation for an experiment to determine the radial distribution of the negative atomic oxygen ion in the positive column of a plasma discharge. Lee's theory is modified to apply to a discharge of square cross section. A new design for a discharge tube is presented. The operating characteristics of this tube are investigated: current-voltage measurements are made showing operating regimes of the T-form and H-form of the discharge, and acoustic waves are shown to exist in the T-form region. Three experimental designs are presented to determine the radial density of the oxygen anion, each involving photodetachment.
