Presently FLNR reconstructs the U400 cyclotron. The new, U400R cyclotron is intended to accelerate the ion beams with A/Z from 4 to 12 up to the energy 0.78 – 27 MeV/nucleon. The wide range of the magnetic field levels from 0.8T till 1.8T allows to make a smooth variation of the beam energy over the range ±60% from nominal. For optimization of the magnetic field the 14 pairs of radial correcting coils are used. The numerical formation of the magnetic field is carried out. At the present work the main problems and solutions of the magnetic field design are described.

The transverse particle distribution of the ion beam produced in the Electron Cyclotron Resonance Ion Source (ECRIS) is considered. It is shown that the beam emittance at the entrance of the cyclotron spiral inflector is strongly dependent on directions of both the ECRIS and cyclotron magnetic fields. The changing of the beam rms emittance and bunch lengthening in the spiral inflector for every considered distribution are obtained in the computer simulation.
