The S.I.N. Ring Cyclotron after One Year of Operation

The 590 MeV isochronous ring cyclotron produced its first extracted proton beam in January 1974. One year later the situation is as follows: Two external targets with a total of six secondary pion beam lines and one neutron line are operational and a number of experiments with medium energy pions have been performed. The superconducting muon channel is operating successfully and produces the highest muon fluxes ever recorded. Transmission through the ring cyclotron is more than 95%. Typical currents on the targets are 5 μA, the maximum being 25 μA.
