Zbasnik Superconducting Super Collider Laboratoryt 2550 Beckleyrneade Ave Dallas, TX 75237-3997 USA This paper reports on the efforts that have led to the development of a viable design for an SSC 80K Synchrotron Radiation Liner System. The liner is one method under consideration to minimize the presence of photodesorbed gases in the particle beam line vacuum, thereby assuring acceptable operational availability of the SSC Collider. The 80K liner is also aimed at improving the Collider's cryogenic thermal efficiency, which would allow a potential luminosity upgrade. Trade studies, engineering analyses, concept evaluation, and design are introduced. This paper also briefly discusses the preliminary consideration of lower-temperature (20K and 4K) liners.
