RESEARCH ON CESIUM-VAPOR CELLS EMPLOYING CARBIDE CATHODES

Abstract

The performance of Cs vapor thermionic cells employing carbide emitters was studied. Vacuum emission measurements were made on a series of samples consisting of polycarbides of U and Zr. Certain carbide samples were incorporated into Cs cells and studies were made of the electrical output characteristics. Results indicated that the cells operate in a discharge mode for Cs pressures exceeding 0.1 mm Hg and that maximum power output decreases linearly as the interelectrode spacing increases. Observations were made of the effect of Cs adsorption on carbide and refractory metal emitter materials. (Author)
