The support and cryostat system for doubler magnets

This paper describes the support design, and mass production engineering of the Energy Doubler Dipole Cryostats. The coils, which are surrounded by a warm iron yoke, must be supported against high magnetic forces resulting from errors in the concentricity between the coil and iron yoke. The whole support system must be further contained within a one inch radial distance. The support system developed to meet these criteria which is a combination of heat-sunk G-11 blocks, meets the requirement of total helium heat leak of 5W per magnet. Data will be presented on both mechanical and thermal performance. The unique quality assurance system used by both industrial and Fermilab fabricators will be discussed.
