In excess of a thousand metal vacuum seals are used in the vacuum system of the Alternating Gradient Synchrotron (AGS) at Brookhaven National Laboratory. Numerous elastomer seals are used throughout the AGS to seal large beam component chambers. An accelerator upgrade program is being implemented to reduce the AGS operating pressure by a factor of 100 and improve the reliability of the vacuum system. This paper describes work in progress on metal and elastomer vacuum seals to help meet these two objectives. Tests are reported on the sealing properties of a variety of metal seals used with different sealing surfaces. Results are also given on reversible sorption properties of certain elastomers. © 1990.
