| Abstract |
The JSC "NIIEFA" is designing a cyclotron system intended to accelerate ions with a mass-to-charge ratio of 3-7 in the energy range of 7.5-15 MeV per nucleon. The variety of ions, the range of changes in their energy, and the intensity of the beams provide conditions for a wide range of basic and applied research, including for solving a number of technological tasks. The cyclotron electromagnet has an H-shaped design with a pole diameter of 4 meters and a four-sector mag-netic structure. In the basic mode, the dependence of the induction on the radius corresponding to the isochronous motion is realized by turning on the main coil only through the shape of the central plugs, sector side plates, and sector chamfers. For other modes of isochronous ac-celeration, the current in the main coil is changed and cor-rection coils are tuned. The resonance system consists of two resonators with an operating frequency adjustable from 13 to 20 MHz. The final stage of the RF generator is installed close to the resonator and is connected to it by a conductive power input device. The external injection system generates and separates ions with a given A/z ratio. The injection energy is chosen such that the Larmor radius is constant, which allows us-ing an inflector of unchanged geometry for the entire list of ions. The transportation system forms beams of accelerated ions with specified parameters and delivers them to sample irradiation devices. Computer control of the cyclotron is provided.
