In 1957, the Synchrocyclotron (SC), a 600 MeV proton accelerator, is CERN’s first accelerator to begin operation, providing beams for the Laboratory’s first experiments from 1958 onwards. In 1967, it begins supplying particles for a dedicated nuclear research facility called ISOLDE. The SC is decommissioned in 1990.
