R. Bossert et al., Mechanical design and performance of the Fermilab high gradient quadrupolemodel magnets for the LHC interaction regions, IEEE APPL S, 9(2), 1999, pp. 459-462
The mechanical design of the Fermilab high gradient quadrupole (HGQ) magnet
cold mass is presented, along with its expected behavior and performance u
nder fabrication and operational conditions. Coil stresses, end forces and
collared coil diameter measurements obtained during fabrication and cryogen
ic testing are also presented, and are discussed in the context of expected
behavior and feedback into the design.
