The Large Hadron Collider - CERN
WEBSep 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 …
The birth of the Web | CERN
WEBIn 2013, CERN launched a project to restore this first ever website: info.cern.ch. On 30 April 1993, CERN put the World Wide Web software in the public domain. Later, CERN made a release available with an open licence, a more sure way to maximise its dissemination. These actions allowed the web to flourish.
The Standard Model - CERN
WEBThe Standard Model. The Standard Model explains how the basic building blocks of matter interact, governed by four fundamental forces. The theories and discoveries of thousands of physicists since the 1930s have resulted in a remarkable insight into the fundamental structure of matter: everything in the universe is found to be made from a few ...
The Higgs boson - CERN
WEBOn 4 July 2012, the ATLAS and CMS collaborations announced the discovery of a new particle to a packed auditorium at CERN. This particle had no electrical charge, it was short-lived and it decayed in ways that the Higgs boson should, according to theory. To confirm if it really was the Higgs boson, physicists needed to check its “spin ...

Antimatter - CERN
WEBAntimatter. In 1928, British physicist Paul Dirac wrote down an equation that combined quantum theory and special relativity to describe the behaviour of an electron moving at a relativistic speed. The equation – which won Dirac the Nobel Prize in 1933 – posed a problem: just as the equation x 2 = 4 can have two possible solutions (x = 2 or ...
Accelerators - CERN
WEBAccelerators 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 necessary, getting an energy boost at each turn.
