The useful aperture in the pole gap is 150 x 62 mm (horizontal x vertical) for a magnetic length of 1 m. The total mass of the iron is 4500 kg, and the developed length of the MgB2 cable is 85 m.

Many physics experiments at CERN require moderate magnetic fields (around 2 tesla) in a large gap over a large volume. These are currently created by normal-conducting, iron-dominated electromagnets. While robust and reliable, these resistive magnets require significant electrical power – in the MW range – and therefore can be costly to operate.
