An investigation of the relationship between the photoemissive characteristics and the surface elemental compositon of Ag-O-Cs photocathodes was carried out. In support of this investigation it became desirable to examine the validity of the photocathode model proposed by Borziak, Bibik, and Kramerenko with respect to more recently acquired photoelectron energy distribution EDC and Auger electron emission data. The basis for this model is that the Ag-O-Cs photocathode is a composite of metallic silver particles dispersed in a cesium oxide matrix. With this premise, the photoelectric sensitivity in the ultraviolet lambda 300 nm is ascribed to the cesium oxide and that in the visible and infrared lambda 300 nm to the metallic silver particles.
