The Large Hadron Collider (LHC) is the world’s largest and most powerful particle accelerator. It first started up on 10 September 2008, and remains the latest addition to CERN’s accelerator complex. The LHC consists of a 27-kilometre ring of superconducting magnets with a number of accelerating structures to boost the energy of the ...

The Large Hadron Collider (LHC) is the most powerful particle accelerator ever built. The accelerator sits in a tunnel 100 metres underground at CERN, the European Organization for Nuclear Research, on the Franco-Swiss border near Geneva, Switzerland.

The tunnel would initially house the FCC-ee, an electron–positron collider for precision measurements offering a 15-year research programme from the mid-2040s. A second machine, the FCC-hh , would then be installed in the same tunnel, reusing the existing infrastructure, similar to when the LHC replaced LEP .

The collider's energy eventually topped 209 GeV in 2000. During 11 years of research, LEP's experiments provided a detailed study of the electroweak interaction. Measurements performed at LEP also proved that there are three – and only three – generations of particles of matter.

A muon collider could therefore run using less energy, for example a 10 TeV muon collider could be competitive with a 100 TeV proton collider. The idea of a muon collider is not new – it was first introduced 50 years ago – but a major technical challenge results from the muon’s short lifetime.

Particles get their mass by interacting with the Higgs field; they do not have a mass of their own. The stronger a particle interacts with the Higgs field, the heavier the particle ends up being.

The Compact Linear Collider An international collaboration is developing a future high-energy machine to collide electrons and positrons head-on at energies up to several TeV The Compact Linear Collider (CLIC) is a proposed accelerator that is being designed as an addition to CERN’s accelerator complex .

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 dark matter.

The Large Hadron Collider (LHC) can achieve an energy that no other particle accelerators have reached before, but Nature routinely produces higher energies in cosmic-ray collisions. Concerns about the safety of whatever may be created in such high-energy particle collisions have been addressed for many years.
