SSC Collider Dipole Cryostat

Abstract

The Superconducting SuperCollider (SSC) project required almost 8000 dipole magnet cryostats. These cryostats had design requirements that included low heat leak, structural stability and cost minimization. Detailed designs were developed and numerous prototype magnets were built and tested. While the SSC project did not continue, many aspects of the SSC dipole magnet cryostats were used in later projects such as the LHC and ILC. This chapter describes the SSC dipole magnet cryostat design including design criteria, thermal insulation systems, structural supports and interconnects. Test results from prototypes, particularly in the area of heat leak are also presented.
