The Large Hadron Collider - CERN The Large Hadron Collider (LHC) is the world’s largest and most powerful particle accelerator that pushes protons or ions to near the speed of light 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
The Future Circular Collider - CERN The tunnel would initially house the FCC-ee, an electron–positron collider for precision measurements offering a 15-year research programme from the late 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
Facts and figures about the LHC - CERN "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 "Collider" because the particles form two beams travelling in opposite directions, which are made to collide at four points around
The Large Electron-Positron Collider - CERN 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
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
ALICE detects the conversion of lead into gold at the LHC In a paper published in Physical Review Journals, the ALICE collaboration reports measurements that quantify the transmutation of lead into gold in CERN’s Large Hadron Collider (LHC) Transforming the base metal lead into the precious metal gold was a dream of medieval alchemists This long-standing quest, known as chrysopoeia, may have been motivated by the observation that dull grey
Grand collisionneur de hadrons - CERN Le LHC est l’accélérateur de particules le plus grand et le plus puissant du monde C'est un anneau de 27 kilomètres de circonférence, formé de milliers d'aimants supraconducteurs et doté de structures accélératrices pour accroître l'énergie des particules à chaque passage Le Grand
And they’re off! The 2025 LHC physics season gets underway (Image: CERN) Today at 13h51, the engineer in charge of the LHC at the CERN Control Centre announced that stable beams had returned to the Large Hadron Collider (LHC), marking the start of the 2025 physics data-taking campaign, the fourth year of the LHC's third operating period (Run 3*) The 2025 campaign will start with proton collisions at 13 6 TeV, and the proposed integrated luminosity
The accelerator complex - CERN In the Large Hadron Collider (LHC) – the last element in this chain – particle beams are accelerated up to the record energy of 6 8 TeV per beam Linear accelerator 4 ( Linac4 ) became the source of proton beams for the CERN accelerator complex in 2020
Record data for the LHC in 2024 - CERN The particles completed a final lap of honour around the LHC on 23 November, bringing the 2024 run of the Large Hadron Collider (LHC) to a close The LHC performed beautifully in its tenth year of operation During the proton run, which began on 25 April and ended on 16 October, an exceptional volume of data was collected at a collision energy of 13 6 teraelectronvolts (TeV) The integrated
