Large Hadron Collider reaches its first stable beams in 2024
On 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, meaning more collisions for the experiments to ...
Antimatter - CERN
The Antiproton Decelerator (AD) is a unique machine that produces low-energy antiprotons for studies of antimatter, and “creates” antiatoms.
Accelerators - CERN
Accelerators use electromagnetic fields to accelerate and steer particles. Radiofrequency cavities boost the particle beams, while magnets focus the beams and bend their trajectory.. In a circular accelerator, the particles repeat the same circuit for as long as …
What's so special about the Higgs boson? - CERN
Real CMS proton-proton collision events in which 4 high energy muons (red lines) are observed. The event shows characteristics expected from the decay of a Higgs boson but is also consistent with background Standard Model physics processes.

Sep 10, 2008 · 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 particles along the way.
Summer Student Programme - CERN
The CERN Summer Student Programme offers students pursuing bachelor’s or master’s degrees in physics, computing, engineering and maths a unique opportunity to join in the day-to-day work of research teams participating in experiments at CERN in Geneva, Switzerland. Beyond the outstanding first-class scientific value of their stay, the selected students will find working in a ...
Facts and figures about the LHC - CERN
What are the detectors at the LHC? There are nine experiments installed at the LHC: ALICE, ATLAS, CMS, LHCb, LHCf, TOTEM, MoEDAL-MAPP, FASER and [email protected] use detectors to analyse the myriad of particles produced by collisions in the accelerator. These experiments are run by collaborations of scientists from institutes all over the world.
Extra dimensions, gravitons, and tiny black holes | CERN
Why is gravity so much weaker than the other fundamental forces? A small fridge magnet is enough to create an electromagnetic force greater than the gravitational pull exerted by planet Earth.
