The dipoles required in the Intersection Regions (IRs) of the LHC have field and aperture requirements close to those of the RHIC arc dipole magnets. Thus the superconducting coils developed for those magnets can be used in a cost-effective dipole design that satisfies CERN’s requirements. Under the auspices of the US/CERN LHC Collaboration, the required magnets will be built at BNL.
