	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.

	JSC "NIIEFA" is designing a cyclotron system that gen-erates intensive proton beams with final energy in the range of 30-250 MeV. We have adopted a non-standard technical solution: at the energy of less than 125 MeV negative hydrogen ions are accelerated with the extrac-tion of protons by the stripping device; at higher energies protons are accelerated, and the beam is extracted by a deflector and a magnetic channel. The isochronous de-pendence of the magnetic field on the radius for different final energies is provided by changing the current in the main coil and tuning the correction coils. The cyclotron electromagnet has an H-shaped design with a pole diameter of 4 meters, a four-sector magnetic structure, and high spirality sectors. The dees of the reso-nance system are formed by delta electrodes and placed in the opposite valleys; stems are brought outwards through holes in the valleys. The operating frequency range is 24-33.2 MHz. The power of the RF generator is 60 kW. The cyclotron complex is equipped with a branched beam transport system and target devices for applied re-search on the radiation resistance of materials. Computer control of the cyclotron and its associated systems is provided.
