Abstract

Fermilab began operating a re-designed satellite refrigerator system in November 1993. Upgrades were installed to operate the Tevatron at a magnet temperature of 3.5K, approximately 1K lower than the original design. Refrigerator upgrades included new valve boxes, larger reciprocating expanders, the installation of cold vapor compressors, new sub atmospheric instrumentation and an entirely new distributed controls system.

Cryogenic system reliability data for Colliding Physics Run 1B is presented emphasizing a failure analysis for each aspect of the upgrade. Comparison to data for Colliding Physics Run 1A (previous to the upgrade) is presented to show the impact of a major system overhaul. New operational problems and their solutions are presented in detail.
