  1. Superconducting dipole magnet for CBM. The status of the SCdipole magnet for project CBM. E.A. Matyushevskiy, P.G. Akishin, A.V. Alfeev, V.S. Alfeev, V.V. Borisov, V.V. Ivanov, E.I. Litvinenko, A.I. Malakhov. Authors present the engineering project of superconducting dipole magnet for СБМ experiment. Parameters of the magnet corresponds to last requirements of project CBMto magnetic system on formation of the working aperture and sizes of a field in a gap of the magnet and the minimal the field in area RICH. Tarulinna, Sortavala, Karelia 02.06.2009 y.

  2. SC dipole magnet with the aperture 1.3x1.6 m in a gap of the magnet and length along a beam equal 1 m is shown.
