The results of the research program were the determination of the effects of the presence of various inert background gases on the electron energy distribution, electron number density, and potential variation in the plasma of a cesium ignited-mode thermionic converter. Plasma properties are reported for a number of different ratios of inert gas background pressure to cesium pressure for the addition of inert species of xenon, krypton, and neon gases. The report relates findings of this investigation to the transport and ionization processes taking place in the ignited-mode converter through the use of recently available electron-cesium heavy particle cross-section information as well as the detailed information on the plasma properties obtained from the investigations reported in AD-621 276. In conjunction with the electrostatic probe measurements, spectroscopic investigations were conducted to determine the number density of electrons existing in the plasma. Also included in this report are a summary of the over-all accomplishments resulting from these investigations and a bibliography of the publications generated as a result of this study. Author
