SKIF (Siberian ring photon source) is a fourth generation synchrotron radiation source. This installation will consist of 3 main parts: a linear accelerator with an energy of 200 MeV; a booster - a synchrotron with a maximum energy of 3 GeV and an orbit length of 158 m; storage ring with 16-fold symmetry, energy 3 GeV and a perimeter of 476 m Thanks to this synchrotron source, it will be possible to: receive beams of micro- and nano-sizes; to carry out X-ray structural analysis; study shock-wave, hypersonic and explosive processes; investigate the local and magnetic structure of matter. Within the framework of this project, 3D modeling of several types of dipole magnets was carried out for the storage ring: 1. C-designed dipole magnets (BMA) with an effective length of Leff = 69 cm and a magnetic field in the center of B = 0.53 T, which will be located in the rectilinear intervals of the ring with large beta-x; 2. C-designed dipole magnets (BDA) with Leff = 130 cm, magnetic field in the center B = 0.55 T, gradient G = -7.9 T / m, which will be in the soft X-ray region; 3. C-designed dipole magnets (BDC) with Leff = 47 cm, magnetic field in the center B = 0.46 T, gradient G = -10.7 T / m, which will be located in the hard X-ray cell; 4. Permanent magnet with a field of B = 2 T. The required field quality for the dipoles under consideration should be no worse than 5 × 10⁻⁴. ER -
