The Large Hadron Collider | CERN The Large Hadron Collider The Large Hadron Collider (LHC) is the world’s largest and most powerful particle accelerator It consists of a 27-kilometre ring of superconducting magnets with a number of accelerating structures to boost the energy of the particles along the way
CERN releases report on the feasibility of a possible Future Circular . . . 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 over a thousand physicists and engineers across the globe, the report presents an overview of the different aspects related to the potential implementation of such a project The FCC is a proposed
The Future Circular Collider | CERN The Future Circular Collider (FCC) study is developing designs for higher performance particle colliders that could follow on from the Large Hadron Collider (LHC) once it reaches the end of its High-Luminosity phase The FCC Feasibility Study, which delivered its report on 31 March 2025, investigated the technical and financial viability of the FCC at CERN The study looked at geological and
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 to the group of particles called hadrons
Accelerators - CERN Muon Collider AWAKE Past accelerators Many accelerators developed several decades ago are still in operation The oldest of these is the Proton Synchrotron (PS), commissioned in 1959 Others have been closed down, with some of their components being reused for new machines, at CERN or elsewhere Travel back into the past of CERN accelerators
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, the Large Electron-Positron (LEP) collider was – and still is – the largest electron-positron accelerator ever built
The Higgs boson - CERN 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 particles called photons In the Higgs boson's case, the field came first The Higgs field was proposed in 1964 as a new kind of field that fills the entire Universe and gives mass to all elementary
FCC - CERN The Future Circular Collider (FCC) is an international design study with emphasis on a hadron collider with a centre-of-mass energy of the order of 100 TeV in a new 80-100 km tunnel as a long-term goal
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 Before they reach the LHC, the particles are sped up in a series of interconnected linear and
