A novel superconducting cyclotron for therapy and radioisotope production

The design of a four sector compact superconducting cyclotron, able to accelerate up to 250 A MeV light ions with charge/mass ratio 0.5, is in progress. Light ions like 12 C 6+ , 10 B 5+ , 6 Li 3+ will be extracted by electrostatic deflectors while H 2 + ions can be extracted also by stripping, therefore a beam power of 10 kW or more is available. This cyclotron can be used for radiotherapy with protons or carbon ions and also to drive a facility for production of unusual medical radioisotopes. The main parameters and some features of the machine are here presented.
