The CERN convention was signed in 1953 by the 12 founding states Belgium, Denmark, France, the Federal Republic of Germany, Greece, Italy, the Netherlands, Norway, Sweden, Switzerland, the United Kingdom and Yugoslavia, and entered into force on 29 September 1954. The Organization was subsequently joined by Austria (1959), Spain (1961-1969, re-joined 1983), Portugal (1985), Finland (1991), Poland (1991), Czechoslovak Republic (1992), Hungary (1992), Bulgaria (1999), Israel (2014), Romania (2016) and Serbia (2019). The Czech Republic and Slovak Republic re-joined CERN after their mutual independence in 1993. Yugoslavia left CERN in 1961.
What does membership mean?
Member States have special duties and privileges. They make a contribution to the capital and operating costs of CERN’s programmes, and are represented in the Council, responsible for all important decisions about the Organization and its activities.
Who are our Member States?
Today CERN has 23 Member States: Austria, Belgium, Bulgaria, Czech Republic, Denmark, Finland, France, Germany, Greece, Hungary, Israel, Italy, Netherlands, Norway, Poland, Portugal, Romania, Serbia, Slovak Republic, Spain, Sweden, Switzerland and United Kingdom.
Who has Observer status?
Over 600 institutes and universities around the world use CERN’s facilities. Funding agencies from both Member and Non-Member States are responsible for the financing, construction and operation of the experiments on which they collaborate. CERN spends much of its budget on building machines such as the Large Hadron Collider and it only partially contributes to the cost of the experiments.
Can non-members join CERN?
Non-Member States with co-operation agreements with CERN include Albania, Algeria, Argentina, Armenia, Australia, Azerbaijan, Bangladesh, Belarus, Bolivia, Brazil, Canada, Chile, China, Colombia, Costa Rica, Ecuador, Egypt, North Macedonia, Georgia, Iceland, Iran, Jordan, Korea, Malta, Mexico, Mongolia, Montenegro, Morocco, New Zealand, Peru, Saudi Arabia, South Africa, United Arab Emirates and Vietnam.
CERN also has scientific contacts with Cuba, Ghana, Ireland, Latvia, Lebanon, Madagascar, Malaysia, Mozambique, Palestinian Authority, Philippines, Qatar, Rwanda, Singapore, Sri Lanka, Taiwan, Thailand, Tunisia, Uzbekistan.
How else do Member States exchange information?
Thematic forums bring together experts from CERN and Member States to exchange information and develop coherent strategies. Associate Member States may also participate. Existing forums are:
- Industrial liaison officer (ILO) forum provides advice on doing business with CERN and supports firms in their local regions.
- Knowledge transfer (KT) forum transfers CERN’s knowledge to science, technology and industry.
- Scientific computing forum explores requirements and solutions for data-intense computing applications of publicly funded research.
- Teacher and student forum focuses on pre-university educational activities.
There are also recognised networks with their own governance:
- European Particle Physics Communication Network (EPPCN) is a network of communication specialists.
- International Particle Physics Outreach Group (IPPOG) is a worldwide network for scientific education and outreach.
