“…The cold mass shape has been established using a laser tracker Leica TM [40]. The tight tolerances on the longitudinal shape have been fixed to ±1 mm along the reference orbit, and to ±0.3 mm at the end of the magnet, where the multipolar correctors (spool pieces) are located.…”

Superconducting magnets have played a key role in advancing the energy reach of proton synchrotrons and enabling them to play a major role in defining the Standard Model. The problems encountered and solved at the Tevatron are described and used as an introduction to the many challenges posed by the use of this technology. The LHC is being prepared to answer the many questions beyond the Standard Model and in itself is at the cutting edge of technology. A description of its magnets and their properties is given to illustrate the advances that have been made in the use of superconducting magnets over the past 30 years.

Abstract-The series production of the LHC main dipole magnets was completed in November 2006. This paper presents the organization implemented at CERN and the milestones fixed to fulfill the technical requirements and to respect the master schedule of the machine installation. The CERN organization for the production follow-up, the quality assurance and the magnet testing, as well as the organization of the three main contractors will be described. A description of the design work and procurement of most of the specific heavy tooling and key components will be given with emphasis on the advantages and drawbacks.

“…The collared coil and the yoke laminations are enclosed by a shrinking cylinder welded with 150 MPa circumferential stress. The welding also imposes the desired curvature on the cold mass, which corresponds to a nominal sagitta of 9.14 mm [40]. The main parameters and performance of the cold mass are given in Table 5 and compared to Tevatron, HERA and RHIC dipoles.…”
