STUDY OF ADSORPTION OF GASES ON SOLIDS IN THE HIGH VACUUM RANGE

Abstract

An ultra-high-vacuum system for gas adsorption measurements at low pressures was set in opeation and data are reported on the processing of the system and on the composition of the final gas ambient under several operating conditions. When the system is open to the pumps total pressures of less than 10 to the -11th power Torr were measured. When the system is isolated from the pumps by means of high-vacuum valves, a linear inrease of He partial pressure was measured over a 7 day period up to a pressure of 10 to the minus 6th power Torr. For a short time argon appeared to a pressre of 5 x 10 to the -10th power orr and later disappeared. (Author)
