Abstract

The CEBAF refrigerator is designed to produce 4620 watts of refrigeration at 2.0 K, another 180 watts at 2.14 K plus 4.5 K liquid and higher temperature cooling for shields. Several design features are described, including a modular concept for the 2 K and 4.5 K refrigerator sections and the use of multistage centrifugal cryogenic compressors to achieve the 2 K. The development program for the centrifugal cryogenic compressors is discussed. Some startup information is also provided.
