The Large Hadron Collider - CERN
WEBSep 10, 2008 · LHC tunnel pt1 various angle (Image: CERN) 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 …
Accelerators - CERN
WEBThe CERN accelerator complex accelerates protons, but also nuclei of ionized atoms (ions), such as the nuclei of lead, argon or xenon atoms. Some LHC runs are thus dedicated to lead-ion collisions. The ISOLDE facility accelerates beams of exotic nuclei for nuclear physics studies. The energy of a particle is measured in electronvolts.
The accelerator complex - CERN
WEBThe accelerator complex at CERN is a succession of machines that accelerate particles to increasingly higher energies. Each machine boosts the energy of a beam of particles before injecting it into the next machine in the sequence. In the Large Hadron Collider (LHC) – the last element in this chain – particle beams are accelerated up to the ...
How an accelerator works - CERN
WEBAn accelerator comes either in the form of a ring (a circular accelerator), where a beam of particles travels repeatedly round a loop, or in a straight line (a linear accelerator), where the particle beam travels from one end to the other. At CERN a number of accelerators are joined together in sequence to reach successively higher energies.
Large Hadron Collider reaches its first stable beams in 2024 - CERN
WEBOn Friday 5 April, at 6.25 p.m., the LHC Engineer-in-Charge at the CERN Control Centre (CCC) announced that stable beams were back in the Large Hadron Collider, marking the official start of the 2024 physics data-taking season. The third year of LHC Run 3 promises six months of 13.6 TeV proton collisions at an even higher luminosity than before ...
Facts and figures about the LHC - CERN
WEBThe accelerator sits in a tunnel 100 metres underground at CERN, the European Organization for Nuclear Research, on the Franco-Swiss border near Geneva, Switzerland. What is the LHC? The LHC is a particle accelerator that …
The Future Circular Collider - CERN
WEBThe 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 ongoing FCC Feasibility Study, expected to conclude in 2025, is investigating the technical and financial viability of the ...
Extra dimensions, gravitons, and tiny black holes | CERN
WEBWhat exactly we would detect would depend on the number of extra dimensions, the mass of the black hole, the size of the dimensions and the energy at which the black hole occurs. If micro black holes do appear in the collisions created by the LHC, they would disintegrate rapidly, in around 10 -27 seconds. They would decay into Standard Model or ...
Experiments - CERN
WEBCERN’s experimental programme has consisted of hundreds of experiments spanning decades. Among these were pioneering experiments for electroweak physics, a branch of physics that unifies the electromagnetic and weak fundamental forces. In 1958, an experiment at the Synchrocyclotron discovered a rare pion decay that spread CERN’s …
Large Hadron Collider restarts - CERN
WEBApr 22, 2022 · The world’s largest and most powerful particle accelerator has restarted after a break of more than three years for maintenance, consolidation and upgrade work. Today, 22 April, at 12:16 CEST, two beams of protons circulated in opposite directions around the Large Hadron Collider’s 27-kilometre ring at their injection energy of 450 billion …
