A New Multidisciplinary Separated-Sector Cyclotron Facility

A separated-sector cyclotron with a maximum proton energy of 200 MeV has been proposed for a multidisciplinary accelerator facility for the Republic of South Africa. At energies up to 100 MeV, proton and deuteron currents of the order of 100 microamps will be available for routine isotope production and neutron therapy. Light-ion beams for particle physics and chemistry will be delivered with maximum currents of about 10 microamps and maximum energies in excess of 50 MeV per nucleon. Heavy-ion beams of between 15 and 50 MeV per nucleon are planned with maximum intensities of between 10 particle-nanoamps and 1 particle-microamp, depending on the type of ion. This proposal has recently been approved and progress in the design of the cyclotron and related aspects of the proposed facility is reported here.
