The report summarizes a study of factors in basic thermionic converter research which are potentially important to the success of the engineering programs. An elementary phenomenology-based analytical description of cesium diode converter operation is formulated to serve as an intuitive bridge between the device engineering and physical electronic technologies. The theoretical description of the emission properties of surfaces immersed in cesium vapor is generalized and extended to explain effects of additives and impurities which have been poorly understood. Thermionic emission of negative cesium ions from the collector is explored as a possible mechanism causing anomalous effects at the collector. A synopsis of the interrelation of basic converter physics and thermionic reactor design is developed which indicates that substantial engineering advances are achievable primarily through reduction of electron energy losses in the converter.
