Production of Dipoles for LHC

The dipole magnets for the LHC accelerator ring are used to keep the particles on track. Among other magnets, the accelerator ring consists of 1,132 dipole magnets, each 15 m long and weighing about 30 t.

The inner coil is built from superconducting material for generating a magnet field of about 8 Tesla; this requires chilling the magnets to -271°C.

Bilfinger Noell won the contract for developing the prototype, for pre-serial production and serial production. Thus, Bilfinger Noell supplied a third of the magnets for the whole accelerator ring.

Customer: CERN, Geneva, Switzerland

Project duration: 1999 - 2006
