Cryostat design for the Superconducting Super Collider 50 mm aperture dipole magnet

The design of the SSC (Superconducting Super Collider) dipole magnet cryostat is described, and discussions of the thermal, structural, and dynamic considerations involved in the development of each of the major systems are included. The SSC development program has afforded the opportunity to extend the design of cryostats for superconducting magnets far beyond the state of the art achieved at the end of the Fermilab Tevatron program. Advances in new materials technology have opened up options for cryostat designers in both thermal and structural materials. Strict limits on allowable heat load have made it necessary to develop new mechanisms for structural support and thermal shielding. The end result is a cryostat design which meets the demands of the SSC and which will serve as the starting point for the development of other magnet systems.
