To minimize the expenditures while designing the cyclotron an attempt was made to use at most the existing synchrocyclotron infrastructure, i.e. the building with the radiation shielding, the bridge crane for 30 tones, the electric power, water cooling, ventilation systems, etc. The iron yoke of the existing synchrocyclotron magnet model is used for a magnet system. The special magnetic structure with very low value of the flatter 0.025 and extremely high spiral angle about 60 degree in the radii range from 0.3 up to 0.9 m was developed to provide acceleration of H-minus ions up to energy 80 MeV in the magnet with extraction radius 0.9 m. Special attention was paid to thoroughly study effects of the highly spiraled structure: decrease of the flatter with introduction of the spiral angle, discrepancy between the magnetic and geometrical spiral angles, the spiral angle inefficiency in the cyclotron central region.

A СС1-3 cyclotron system has been designed to be installed in the Vinca Institute of Nuclear Sciences, Belgrade, Serbia. This system will be operated in the laboratory of nuclear-physical methods of the elemental analysis. The system includes a compact cyclotron and a system for beam shaping with specified energy characteristics. The cyclotron ensures the acceleration of negative hydrogen ions up to energy in the range from 1 to 3 MeV and a beam of protons is extracted by stripping on a thin carbon foil. The beam-shaping system ensures the beam of protons with a spectrum width not more than 0.1%. The main unit of the beam-shaping system is a magnetic analyzer with a bending angle of 270 deg. To date, the equipment of the cyclotron system has been manufactured and tests have been carried out on test facilities in the D.V. Efremov Institute. Installation will be performed in 2012.

A C-80 cyclotron system is intended to produce proton beams with an energy ranging from 40 up to 80 MeV and current up to 200 mkA. The beams with these parameters will be used for commercial production of a wide spectrum of isotopes for medicine, proton radiation therapy of eye diseases and superficial oncologic diseases as well as for fundamental and applied researches. Manufacturing and installation of the cyclotron equipment and first section of the system for the beam transport to remote targets have been finished. Physical start-up of the cyclotron has been realized. In future, the C-80 cyclotron is supposed to be used as an injector of the C-230 synchrotron, which serves for additional acceleration of the extracted proton beam to energies of the order of 230 MeV. This will allow the Bragg's peak-based treatment procedures to be applied in the proton therapy of oncologic patients.
