Testing magnets for the Large Hadron Collider. The Large Hadron Collider (LHC) is a proposed new accelerator for CERN, the European particle physics laboratory. The job of the magnets is to bend a beam of particles around the 27-km circumference of the accelerator ring, and to keep the beam focused. The large pipe running into the distance (just right of the scientist) is a section containing a focusing magnet between two bending magnets. The cylindrical magnets use superconducting wires to create the intense fields required. The components have to be cooled to 1.8 degrees Kelvin using liquid helium supplied from the large vessel in the foreground.
