Development of high-field superconducting magnets for the large hadron collider

The development of the magnets for the CERN LHC is progressing from the stage of 1 m long model magnets to the construction of full size, 10 m long prototypes. A number of 8 to 10 T single aperture and twin-aperture, 1 m long, dipoles have been built or are being completed in industry. A twin-aperture, 10 m long prototype dipole with its 1.8 K cryostat is being assembled and will be tested soon. Design and construction of quadrupoles, correction magnets and other essential components are being actively pursued in collaboration with several European Institutions and industries.
