An accelerator complex for hadron therapy is under design at the Joint Institute for Nuclear Research (Dubna, Russia). The complex consists of two superconducting cyclotrons. The facility is intended for generating accelerated beams of protons, carbon, and H-2(+) ions. The main cyclotron named K1600 is a separated sector machine, which accelerates carbon ions to the output energy of 400 MeV/u. As an injector, a compact cyclotron K280 is provided for production of proton, carbon, and H-2(+) ion beams with the output energy of 70 MeV/u. The ions are injected into the machine from an ECR ion source. Two extraction methods can be used in the cyclotron. One is based on using an electrostatic deflector and is intended for extracting carbon and H-2(+) ions. The other uses a stripping foil for production of protons from H-2(+) ions. The K280 can also be used as a stand-by facility for medical purposes like treating eye melanoma or for producing radioisotopes. The basic parameters of the cyclotron-injector and detailed investigation of its systems along with the beam dynamics are described.
