Nuclear research organization founded 1954 as a cooperative enterprise among European governments. It has laboratories at Meyrin, near Geneva, Switzerland. It was originally known as the Conseil Européen pour la Recherche Nucléaire but subsequently renamed Organisation Européenne pour la Recherche Nucléaire, although still familiarly known as CERN. It houses the world’s largest particle accelerator, the Large Electron Positron Collider (LEP), with which notable advances have been made in particle physics.
In 1965 the original laboratory was doubled in size by extension across the border from Switzerland into France. In Dec 1994 the 19 member nations of CERN approved the construction of the Large Hadron Collider. It is expected to cost Ł1.25 million and to be fully functional 2005.
Acronym for Conseil Européen pour la Recherche Nucléaire (the European Laboratory for Particle Physics). CERN, a physics research center located in Geneva, Switzerland, is where the original development of the World Wide Web took place by Tim Berners-Lee in 1989 as a method to facilitate communication among members of the scientific community.
