A program to develop an improved vacuum-insulated transfer line coupling was initiated to meet the increasing need for simplicity, low heat leak, small cooldown mass, reliability, and ease of maintenance of cryogenic equipment. Although respectable levels of thermodynamic efficiency have been demonstrated by existing types of couplings, it was felt that a slight compromise in heat leak performance to permit an improvement in maintainability and reliability would be appropriate for a number of applications.
