| Abstract |
This paper presents the results of the calculation of the magnetic system of the cyclotron for accelerating of multicharged ions developed at NIIEFA JSC. The cyclotron complex is designed to generate ions with a mass-to-charge ratio in the range A/Z= 3/7, accelerate them to energies in the range of 7.5-15 MeV per nucleon. The cyclotron electromagnet has a four-sector structure, with a pole diameter of 4 m. Radial coils placed on the poles under the sectors are designed to adjust the magnetic field for providing isochronous acceleration conditions for different ions. A group of azimuthal coils designed to correct the first harmonic of the magnetic field and to center the orbits of the accelerated ion, as well as to ad-just the position of the axial symmetry plane of the magnetic field is located on the sectors. The required magnetic field topology for ion acceleration was formed in the induction range of 1.29-1.6 T. Calculations were per-formed for the 1/8 part of the electromagnet. A mode was chosen in which the dependence of induction on the radius, which provides isochronism, is realized due to the shape of "iron". For this mode with an induction in the center of 1.44 T, the shape of side plates, plugs, and sec-tor chamfers was determined. The currents in radial coils and the main dynamic characteristics of the cyclotron magnetic field for ion acceleration in the energy control range were calculated using the obtained magnetic field maps.
