  NICA is a new accelerator collider complex under construction at the Joint Institute for Nuclear Research in Dubna. The facility is aimed at providing collider experiments with heavy ions up to Gold in the center of mass energy from 4 to 11 GeV/u and an average luminosity up to 1*1027 cm-2 s−1 for Au79+. The collisions of polarized deuterons are also foreseen. The facility includes two injector chains, a new superconducting booster synchrotron, the existing 6 AGeV superconducting synchrotron Nuclotron, and a new superconducting collider consisting of two rings, each 503 m in circumference. The booster synchrotron is based on an iron-dominated "window frame"- type magnet with a hollow superconductor winding analogous to the Nuclotron magnet. The design of superconducting magnets for the NICA booster synchrotron is described. The progress of work on the manufacturing and testing of the magnets is discussed. The calculated and measured values of the characteristics of the magnets are presented. The status of the facility for serial test of superconducting magnets for the NICA and FAIR projects is described.

  NICA booster magnetic system consists of 40 dipole and 48 quadrupole superconducting magnets. Measurement of magnetic field parameters is assumed for each booster magnets. The booster quadrupole is 0.45 m-long, 47.5 mm pole radius magnet with design similar to the Nuclotron type quadrupole magnet. Focusing and defocusing quadrupole magnets are jointed in doublets. They will produce fields up to 21.5 T/m. Two magnetic measurements system with tangential and radial coils arrays were developed and produced. This paper describes the magnetic measurements methods as well as the first results of the magnetic measurements.

  NICA booster magnetic system consists of 40 dipole and 48 quadrupole superconducting (SC) magnets. Measurement of magnetic field parameters is assumed for each booster magnets. At the moment six series dipole magnets are assembled and have passed all tests. Booster dipole magnets are 2.14 m-long, 128 /65 mm (h/v) aperture magnets with design similar to Nuclotron dipole magnet but with curved (14.1 m radius) yoke. They will produce fields up to 1.8 T. The magnetic field parameters will be measured at "warm" (300 K) and "cold" (4.5 K) conditions. The obtained results of magnetic measurements of first five magnets are summarized here.
