Abstract

A significant upgrade to the Fermilab Central Helium Liquefier (CHL) facility’s 4000 liters/hour helium system has been made to support the Laboratory’s Tevatron superconducting accelerator. The upgrade includes a second helium liquefier with a rated capacity of 5400 liters/hour, a fourth reciprocating compressor rated at 750 grams/second, and an improved cryogenic distribution system including liquid helium dewars and pumps. The system design and operating experience to date are discussed.
