History of CERN

  • The Scientists ' vision

    Raul Dautry, Pierre Auger, Lew Kowarski,Edoardo Amaldi and Niels Bohr were among the pionners of creating a European atomic physics laboratory.
  • Searching for the ideal location.

    Searching for the ideal location.
    Geneva was selected as the site for CERN Laboratory.
  • The agreement is accomplished.

    The agreement  is accomplished.
    The CERN Convention established financial contribution of each Member State according to their means.
  • The CERN is born.

    The CERN is born.
    On 29 September 1954 the twelve founding Member State's, Belgium, Denmark, France, the Federal Republic of Germany, Greece, Italy, the Netherlands, Norway, Sweden, Switzerland, United Kingdon and Yugoslavia signed the convention.
  • CERN's first accelerator starts up.

    CERN's first accelerator starts up.
    The accelerator provided beams for CERN's first experiment in particle and nuclear physics.
  • Georges Charpak's contribution.

    In 1968 George Charpak developed the "multiware proportional chamber" a gas- filled box with a large number of parallel detector wires, each connected to individual amplifiers.Linked to a computer it could achieve a counting rate a thousand times better than existing detectors.
  • First proton collisions.

    First proton collisions.
    On 27 January 1971 Kjell Johnsen announced that the world's first interactions from colliding protons had been recorded.
  • The discovery of neutral currents in the Gargamelle bubble chamber.

  • The discovery of W and Z bosons.

    The discovery of W and Z bosons.
    In 1983 , CERN announced the discovery of the W and Z particles, as seen by the UA1 experiment. Carlo Rubbia and Simon van der Meer received the Nobel Prize in physics only a year after the discovery.
  • LEP -beaming a "bright" future.

    LEP -beaming a "bright" future.
    The determination of the number of light neutrino families at the Large Electron Positron Collider operating on the Z boson peak.
  • Conceiving the W.W.W.

    Conceiving the W.W.W.
    Sir Berners- Lee had defined the Web's basic concepts, the html, http and URL, and he had written the first browser. The world's first web page address provided information about the World Wide Web project.
  • The first creation of antihydrogen atoms in the PS210 experiment.

    A team led by Walter Oelert created atoms of antihydrogen for the first time at CERN's Low Energy Antiproton Ring facility.
  • CMS and ATLAS experiments approved.

    CMS and ATLAS are officially approved. Both experiments designed to explore the fundamental nature of matter and the basic forces that shape our universe.
  • ALICE experiment approved.

    ALICE is designed to study quark-gluon plasma, a state of matter that would existed in the first momments of the universe.
  • LHCb experiment approved.

    The experiment will study the phenomenon known as CP violation which would help to explain why matter dominates antimatter in the universe.
  • The discovery of direct CP violation in the NA48 experiment.

  • CERN turns 50

  • Barrel Toroid's magnetic power.

    Barrel Toroid's magnetic power.
    The ATLAS Barrel Toroid was switched on for the first time at CERB on 20 November 2006.It provides a powerful magnetic field for ATLAS, one of the major particle detectors taking data at LHC.
  • LHC introduces a new era.

    LHC introduces a new era.
    The machine is ready to embark on a new era of discovery at the high- energy frontier.
  • The isolation of 38 atoms of antihydrogen.

  • The success of ALPHA experiment.

    The ALPHA experiment succeeded in traping antimater atoms for over 16 minutes.
  • ATLAS and CMS present their latest results in Higgs boson.

    ATLAS and CMS present their latest results in Higgs boson.
  • Discovery of pentaquarks.

    Discovery of pentaquarks.
    The LHCb experiment has reported the discovery of a class particles known as pentaquarks.
