CERN

Von den Anfängen zum Welt-Labor für Teilchenphysik

Beginn der Bauarbeiten am Labor 1954

Geneva was selected as the site for the CERN Laboratory at the third session of the provisional Council in 1952. This choice was approvedin a referendum in the canton of Geneva in June 1953 by 16539 votes to 7332. On 17 May 1954, the first shovel load of earth was dug onthe Meyrin site under the eyes of Geneva officials and members of CERN staff.

Die erste Maschine: CERN Synchro-Cyclotron 1957

The 600 MeV SC (Synchro-cyclotron), built in 1957, was CERN's first accelerator. After 33years of service the SC was closed in 1990.

CERN Proton-Synchrotron 1959

The PS accelerated protons for the first time on 24 November 1959. Since then, the intensity ofits proton beam has increased a thousandfold, and in the course of its history the PS hasaccelerated many other kinds of particle.

Erfindung der Proportionalkammer 1968

Georges Charpak invents the multi-wire proportional chamber, which was to revolutionise thefield of particle detection (1992 Nobel Prize in physics).

Der erste Proton-Proton-Collider (ISR) 1971

The world's first proton-proton collider, the ISR (Intersecting Storage Rings), comes intooperation.

Super-Proton-Synchrotron 1976

The SPS, measuring 7 km in circumference, starts operation as the first cross-borderaccelerator.

Entdeckung der W- u. Z-Bosonen 1983

Discovery of W and Z particles.1984 - Carlo Rubbia and Simon van der Meer are awarded the Nobel Prize in physics for thediscovery of the W and Z bosons, the "messenger" particles of weak interaction processes.

Der Large-Electron-Positon-Collider LEP 1989

The Large Electron-Positron Collider (LEP), a circular collider measuring 27 km incircumference, comes into operation.

Das World-Wide Web 1990

Tim Berners-Lee invents the World Wide Web.

Teilchen-Antiteilchen-Asymmetrie erklärt 1993

Results explaining the infinitesimally small difference between matter and antimatter are produced,subsequently to be refined by the NA48 experiment.

Baubeginn Large-Hadron-Collider (LHC) 1999

Civil engineering for the Large Hadron Collider (LHC) begins.

Näher zum Urzustand der Materie 2000

Creation of a new state of matter, quark-gluon plasma, which probably existed just after the BigBang

Die ersten Anti-Wasserstoffatome 2002

Thousands of antihydrogen atoms are produced and measured for the first time.

CERN feiert 50. Geburtstag 2004

The Globe will be inaugurated on 19 October 2004 as part of the official 50th anniversary celebrations.The Globe will provide an exhibition area and a venue for contacts with CERN's partners in industry.CERN continues its heavy ion programme, with a view to recreating matter as it existed at the birth ofthe Universe.

Die nahe Zukunft: Start des LHC und 2007 der Experimente ALICE, ATLAS, CMS und LHCb

The LHC, the world's largest and most powerful accelerator, will be commissioned ...... along with its four large experiments, ALICE, ATLAS, CMS and LHCb
