Optimization of a large aperture dipole magnet for baryonic matter   studies at Nuclotron
  The aperture of the dipole magnet SP41 has been enlarged for the studies of dense baryonic matter properties at Nuclotron. The homogeneity of the magnetic field in the magnet centre has been improved. The measurement results of the magnetic field components and integral are compared with results of 3D TOSCA calculations.
