Individual contacts with scientists from the then Soviet Union started in 1964. The scientific cooperation with CERN is based on various Agreements and Protocols with the first one signed in 1967. The 1996 Protocol on the participation in the LHC project defined the first Russian contributions to the LHC accelerator. The 2002 Extension to this Agreement brought an additional contribution to the LHC accelerator.

In 2006 Russia signed the Memoranda of Understanding for the Maintenance and Operation (MoUs for M&O) for the four LHC experiments, and the Russian Institutes are active in the LHC physics programmes. A new International Cooperation Agreement with the Russian Federation was signed in April 2019 and is in force since 1 December 2019, paving the Russian engagement with high luminosity upgrade of the LHC.

Russia is an Observer Sate with the special right to attend Restricted Sessions of Council for discussions of LHC matters. 

Russia participates in the WLCG as a federation of several centres at the Tier-2 level (RuTier-2), supporting all four LHC experiments.

Russia participated in the Linac4 project through three R&D projects, fully financed by the International Science & Technology Center (ISTC). Russian institutes are also contributing to the CLIC/CTF3 R&D programme and to many other smaller experiments such as LHCf, AEGIS, ASACUSA, CAST, CLOUD, COMPASS, DIRAC, NA61, NA62, NA63, nTOF and OPERA. Russian scientists are among the biggest user groups of CERN.
