On Friday, the European Centre for Nuclear Research (Cern) released photos of damage to the Large Hadron Collider (LHC), Cern's flagship particle accelerator. The particle accelerator was damaged by a liquid helium leak in September, nine days into an experiment to test fundamental theories of physics by colliding beams of protons inside a 27km ring.
This picture shows two of the most severely broken interconnects, which are between the magnets in LHC sectors three and four. The superconducting magnets, used to direct and focus the proton beams in the experiment, are cooled by liquid helium. An electrical fault caused the liquid helium to leak, resulting in a need for repairs that has put the experiment out of action until at least summer 2009.
