The authors determine the composition of the emitting surface of reduced lead silicate glasses by electron emission and the change in it as a function of the various effects which affect the working of the devices made from RLSG, such as electron multipliers. Preliminary studies were made using an electron spectroscopy for chemical analysis method which showed that the original surface was significantly contaminated by carbon, whose concentration exceeded that of silicon by 7-18 times in different specimens. The surface composition of specimens of reduced lead silicate glasses changes weakly as a function of the reducing regime in hydrogen. Electron bombardment and heating in vaccum at a pressure of 10/sup -9/ torr lead to an increase in the concentration of carbon in the specimen.
