The CERN Hadron Linacs are linear accelerators that accelerate beams of hadrons from a standstill to be used by the larger circular accelerators at the facility.
The first CERN Linac, operating from 1958 until 1992
Linac 2, operating from 1978 to 2018, was used to accelerate protons
Linac 3, currently (as of 2020) used to accelerate ions
Linac4, replacing Linac 2 in 2020, accelerates negative hydrogen ions
The European Organization for Nuclear Research, known as CERN, is an intergovernmental organization that operates the largest particle physics laboratory in the world. Established in 1954, it is based in Meyrin, western suburb of Geneva, on the France–Switzerland border. It comprises 23 member states. Israel, admitted in 2013, is the only non-European full member. CERN is an official United Nations General Assembly observer.
