August 1957, practically on the date foreseen. A press release by CERN on 16 August 1957, stated that the SC, as the third-largest accelerator of its type in the world, had started to work at its full energy. In late 1958, the Synchrocyclotron made its first important contribution to nuclear physics by the discovery of the rare

particle. This discovery helped theorists a lot by proving that this decay really occurs. The Synchrocyclotron was used for an average of 135 hours per week during 1961; it ran continuously every day of the week except Mondays which were reserved for maintenance. The Synchrocyclotron was accelerating

According to the report, the group aimed to finish its work in a year and a complete report to be presented to the European Council for Nuclear Research. A preliminary design drawing of the SC was attached to the report which stated that the work of

was appointed as director of the Synchro-Cyclotron Study Group. After a month, in a report called Provisional Program of Synchro-Cyclotron Study Group, the group decided that they would need a design that could provide 600 MeV protons. The initial objective of the group stated as indicating the scope

In 1969, preparations started to increase the beam intensity and improve the beam extraction efficiency of the SC. It was shut down in June 1973 for modifications. The highly improved machine started working again for physical research with its new name, SC2, in January 1975. In 1990, ISOLDE was

Having served as storage facility since the 1990 shutdown, the SC and its building, the SC hall, were renovated in 2012-2013 to become an exhibition area for visitors, opening September 2013. The exhibition includes a multi-media show about the birth of CERN and the Synchrocyclotron. Using
