Support and cryostat system for doubler magnets

The support design, performance and mass production engineering of the dipole magnet cryostat for the Fermilab Energy Doubler/Saver are described. 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 5 w per magnet. Data are presented on both mechanical and thermal performance. The unique quality assurance system used by both industrial and Fermilab fabricators is discussed
