| Abstract |
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.
