Over 1000 two-in one dipole magnets like this one make up the technological heart of the LHC. Designed to steer proton beams travelling at close to the speed of light around the LHC, their powerful magnetic fields are generated by superconducting cables carrying over 11000 amperes of electric current. Superconductivity is the ability of some materials to lose electrical resistance at very low temperatures. The LHC is installed in an enormous fridge, keeping it at about -271 degrees, or just 1.9 degrees above absolute zero. |
