The dipole magnet is wound of a special cable superconductives, containing 28 and 36 strands on the inner and outer coil layers, respectively.
The strands of the cable are made of Nb-Ti filaments of 6 and 7 mm in diameter (inner and outer layer of the coil) and are embedded in a copper matrix. During the LHC operation at 1.9 K, the two counter-rotating beams follow flat circular trajectories along the 14.3 m long active part of each dipole.
The two orbits are separated by 194 mm which is the nominal distance between the coil axes.
That distance is 420 mm in RF cavities, whereas both beams use a unique pipe when going through detectors.
