The ISOLDE Radioactive Ion Beam Facility, is an on-line isotope separator facility located at the heart of the CERN accelerator complex on the Franco-Swiss border. The name of the facility is an acronym for Isotope Separator On Line DEvice. Created in 1964, the ISOLDE facility started delivering radioactive ion beams to users in 1967. Originally located at the SynchroCyclotron accelerator (CERN's first ever particle accelerator), the facility has been upgraded several times most notably in 1992 when the whole facility was moved to be connected to CERN's ProtonSynchroton Booster (PSB). Entering its 6th decade of existence, ISOLDE is currently the oldest facility still in operation at CERN.
