STUDY OF ADSORPTION OF GASES ON SOLIDS IN THE HIGH VACUUM RANGE,
Abstract
Adsorption data have been obtained for the tungsten-nitorgen system for a second filament. The lowest surface coverage detectable for which the filament is in quasi-equilibrium with its surrounding is 0.55 of a monolayer. In the study of oxygen adsorption on molybdenum, the carbon monoxide background, resulting from reactions between the incoming oxygen and carbon impurities in the omegatron filament, molybdenum anode, and oxide cathode assembly, has been substantially reduced. The major source of carbon monoxide during oxygen adsorption on the molybdenum anode is replacement of previously adsorbed carbon monoxide by oxygen. Some results on sticking probability and molybdenum work function changes with oxygen coverage are presented. (Author)
