Popis: 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 H2 + 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.
