Conceptual deisgn of the SSC cryogenic transfer lines
The SSC cryogenic system requires transfer lines for transporting cryogens between above-ground refrigeration plants and below-ground subcoolers. The transfer lines will be built in modules for convenience in fabrication, handling, and assembly. Each module of the transfer line consists of a vacuum vessel which encloses a bundle of seven cryogenic circuits at 4 K, 20 K, and 80 K. The cryostat includes an 80 K shield and a multilayer insulation (MLI) system for reduction of the heat leaks into the 20 K and 4 K circuits. Heat leaks through various paths are estimated and presented in conjunction with the basic system requirements. Discussions are provided on the design criteria, constraints, and thermal contraction handling techniques.
