Final prototypes, first pre-series units and steps towards series production of the LHC main dipoles

The LHC, a 7 TeV proton collider presently under construction at CERN, requires 1232, superconducting dipole magnets, featuring a nominal field of 8.33 T inside a cold bore tube of 50 mm inner diameter and a magnetic length of 14.3 in. This paper summarises the results of the program of the six LHC...

Description
Summary:The LHC, a 7 TeV proton collider presently under construction at CERN, requires 1232, superconducting dipole magnets, featuring a nominal field of 8.33 T inside a cold bore tube of 50 mm inner diameter and a magnetic length of 14.3 in. This paper summarises the results of the program of the six LHC main dipole final prototypes and presents the performance measurements of the first magnets of the 90 pre-series units currently under manufacture by industry. Results of geometric and magnetic measurements are given and discussed. Finally, the major milestones towards the dipole magnets series manufacture are given and commented.
