Leave SuspensionCERN prepares to expel Russian scientists — but won’t completely cut ties. The European Organization for Nuclear Research (CERN) on Nov. 30, 2024 officially cut ties with research institutes in Russia, in accordance with a decision to allow the cooperation agreement to expire due to the full-scale invasion of Ukraine. The decision means that some 350 Russian scientists will now be expelled from CERN, which is based near Geneva on Swiss and French territory. Cooperation with Russian scientists associated with CERN under different agreements will continue.
Suspended Russia's observer status; halted new collaborations. Following a decision taken by the CERN Council, the Organization’s cooperation with the Russian Federation and the Republic of Belarus will conclude at the expiry in 2024 of the International Cooperation Agreements (ICAs) with the two countries. This decision was taken following the Council’s June 2022 decisions. CERN announced in December 2023 that it would cease cooperation with Russia from November 2024. Scientists overseeing the Russian part of the project are proposing solutions that would allow Russian physicists to continue working at the collider. One option is to organize the work of the Russians “under a neutral flag,” but most administrators are ready to completely stop cooperation. On November 30, 2024 CERN will cease cooperation with about 500 employees with ties to Russia. CERN announced in December 2023 that it would cease cooperation with Russia from November 2024.

One option is to organize the work of the Russians “under a neutral flag,” but most administrators are ready to completely stop cooperation. The European Organization for Nuclear Research (CERN) will end cooperation with up to 500 scientists affiliated with Russian institutions, it said on Sept. 30, because of Russia’s invasion of Ukraine.
