CEC-03 - Cryocoolers (Non-Aerospace)

Contributed Oral Presentation

Turn-key superconducting magnet systems are increasingly conduction-cooled by cryogenerators. Gifford-McMahon systems are reliable and cost effective, but require annual maintenance. The most common maintenance method is to simply replace the cold head of the cryocooler with a reconditioned one. For conduction-cooled magnets, the direct replacement method requires a complicated design with a...

CEC-04 - Cryocoolers (Aerospace)

Contributed Oral Presentation

The regenerator is a critical component of all Stirling and Pulse Tube cryocoolers. It generally consists of a microporous metallic or rare-earth filler material contained within a cylindrical shell. The accurate modeling of the hydrodynamic and thermal behavior of different regenerator materials is crucial to the successful design of cryogenic systems. Previous investigations have used...
