    Mar 31, 2025 · After several years of intense work, CERN and international partners have completed a study to assess the feasibility of a possible Future Circular Collider (FCC). Reflecting the expertise of …

  5. Facts and figures about the LHC - CERN

    Facts and figures about the LHC Why is it called the “Large Hadron Collider”? "Large" refers to its size, approximately 27km in circumference "Hadron" because it accelerates protons or ions, which belong …

  6. The Large Electron-Positron Collider - CERN

    The Large Electron-Positron Collider LEP – the largest electron-positron accelerator ever built – was dismantled in 2000. Its 27-kilometre tunnel now hosts the LHC With its 27-kilometre circumference, …

  7. The Higgs boson - CERN

    Apr 22, 2011 · In our current description of Nature, every particle is a wave in a field. The most familiar example of this is light: light is simultaneously a wave in the electromagnetic field and a stream of …

  8. ATLAS - CERN

    ATLAS is one of two general-purpose detectors at the Large Hadron Collider (LHC). It investigates a wide range of physics, from the Higgs boson to extra dimensions and particles that could make up …

  9. Pulling together: Superconducting electromagnets - CERN

    The Large Hadron Collider (LHC) is currently operating at the energy of 6.5 TeV per beam. At this energy, the trillions of particles circle the collider's 27-kilometre tunnel 11,245 times per second. …

  10. ALICE - CERN

    ALICE (A Large Ion Collider Experiment) is a detector dedicated to heavy-ion physics at the Large Hadron Collider (LHC). It is designed to study the physics of strongly interacting matter at extreme …
