1954-09-29 Paris France


Established on ratification by 9 of the 12 original member countries of a Convention drawn up 1 Jul 1953, Paris, following a resolution, 1950, Florence (Italy), of General Conference of UNESCO and an inter-governmental conference convened by UNESCO, Dec 1951. Replaced H-XH1766 - European Council for Nuclear Research which had come into being on 15 Feb 1952 and by whose acronym the organization is still known. On 13 Sep 1965, an agreement was made with France for the lease of a further 40 hectares of land adjacent to the existing 40 hectares in Switzerland. On 17 Jan 1971 a revised Convention came into force under which an area of 480 hectares (412 in France and 68 in Switzerland) was made available for a proton synchrotron of 450 GeV (the SPS) now installed there. Present site: 112 hectares in Switzerland and 490 hectares in France.

Original aims, according to the Convention: Provide for collaboration among European states in (sub-) nuclear research of a pure scientific and fundamental character and in research essentially related thereto. The Organization shall have no concern with work for military requirements and the results of its experimental and theoretical work shall be published or otherwise made generally available. Since the signing of the Convention in 1954 'nuclear research' has de facto been replaced by 'particle physics research'. In practice, tasks are to: ensure construction and operation of particle accelerators and their necessary ancillary apparatus; define a programme of activities and submit it to the Council; organize and sponsor international cooperation in this field of research, particularly with and among member state laboratories.


Play a leading role in fundamental research in particle physics by constructing and operating experimental apparatus - mainly accelerators and detectors; educate Europe's youth in fundamental particle physics and techniques; transfer technology to member states' industry; bring nations together through research.
