CERN, the European Organization for Nuclear Research, is one of the world’s largest and most respected centres for scientific research. Its business is fundamental physics, finding out what the Universe is made of and how it works.
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 ...
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 ...
The Large Hadron Collider - 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 accelerating structures to boost the energy of the particles along the way.
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.
Antimatter - CERN
The Antiproton Decelerator (AD) is a unique machine that produces low-energy antiprotons for studies of antimatter, and “creates” antiatoms.
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.
Where the web was born | CERN
Tim Berners-Lee, a British scientist at CERN, invented the World Wide Web (WWW) in 1989. The web was originally conceived and developed to meet the demand for automatic information-sharing between scientists in universities and institutes around the world.
How an accelerator works - CERN
In the first part of the accelerator, an electric field strips hydrogen atoms (consisting of one proton and one electron) of their electrons. Electric fields along the accelerator switch from positive to negative at a given frequency, pulling charged particles forwards along the accelerator.
Dark matter - CERN
Galaxies in our universe seem to be achieving an impossible feat. They are rotating with such speed that the gravity generated by their observable matter could not possibly hold them together; they should have torn themselves apart long ago.
