4. CERN – General presentation (1)
Year of Foundation --> 1954 by 12 European States ;
Today --> 2017
Aim of the Organization
CERN has 22 Member States.
Serbia, Cyprus and Slovenia are associate members in the pre-stage to membership ;
Turkey, Pakistan, Ukraine and India are associate members ;
Non-member states with co-operation agreements ;
Scientific contacts.
CERN, the European Organization for Nuclear Research, physicists and engineers are probing the fundamental structure of the universe. They use the world's largest and most complex scientific instruments to study the basic constituents of matter – the fundamental particles
