CERN

CERN, (the abbreviation of Organisation Européene Pour La Recherche Nucléaire; English: European Organization For Nuclear Research) is an international scientific organization established for the purpose of research into high-energy physics. The organization operates for research of a "pure scientific and fundamental character".

CERN headquarters are in Geneva, Switzerland.
The cite covers more than 100 hectares in Switzerland and more than 450 hectares in France.

In the end of 20th century 19 European nations were CERN's memberships. Additionally several nations had "observer" status.

The following are the most important facilities operating in CERN: the 600-MeV synchrocyclotron (1957), the Proton Synchrotron (1959), the Intersecting Storage Rings (ISR; 1971), the Super Proton Synchrotron (SPS; 1976), the Proton-Antiproton Collider (1981) and the Large Electron-Positron Collider (LEP; 1989).
