Status Report on CERN SC

The reconstructed CERN 600 MeV Synchro-Cyclotron has been in operation since 1975. Down time in 1977 has been below 5%; over two hundred experimental physicists use the machine (about half working with the Isotope On Line Separator, Isolde). The beam is normally shared between an internal and an external target. Good macro duty cycle with virtually no RF structure is obtained using a programmed dipole. Since the spring ´78 shutdown, an extracted 3He2+ beam (910 MeV) is available and is being used both by Isolde and for counter experiments. Project studies have shown the feasibility of accelerating 12C4+ to 86 MeV/nucleon (and other ions having Q/A = 1/3); authorization was received in June and the beam is planned for autumn 1979.
