Abstract : The development of microwave diagnostic techniques for measuring the concentration of hydrogen atoms in a discharge and the application of these methods to the study of the rate constants associated with volume and surface recombination is investigated. A microwave cavity spectrometer has been built, especially designed to detect the 1420 Mc/sec. transition in atomic hydrogen corresponding essentially to the zero field hyperfine separation of the ground state. It has been designed so that line shape measurements may be obtained in both the absorption and dispersion modes. One can then relate these measurements to the concentration of atomic hydrogen within a test volume positioned in the cavity, thereby providing a means of measuring recombination rate constants.
