Mechanical design and performance of the Fermilab high gradientquadrupole model magnets for the LHC interaction regions

摘要

The mechanical design of the Fermilab high gradient quadrupole (HGQ) magnet cold mass is presented, along with its expected behavior and performance under fabrication and operational conditions. Coil stresses, end forces and collared coil diameter measurements obtained during fabrication and cryogenic testing are also presented, and are discussed in the context of expected behavior and feedback into the design
