Large Hadron Collider (LHC) is the largest and most powerful particle accelerator. It was built by CERN, the European Organization for Nuclear Research. It lies in a tunnel 27 kilometres in circumference and as deep as 574 ft, beneath the France-Switzerland near Geneva. The LHC is a particle accelerator that pushes protons or ions to near the speed of light. It consists of a 27-kilometre ring of superconducting magnets with a number of accelerating structures that boost the energy of the particles along the way. The aim of the LHC's detectors is to allow physicists to test the predictions of different theories of particle physics, including measuring the properties of the Higgs Boson and searching for the large family of new particles predicted by supersymmetric theories, as well as unsolved questions of physics. The LHC is planned to run over the next 20 years, with several stops scheduled for upgrades and maintenance work. It was first shut down...
