	The Nuclotron-based Ion Collider fAcility (NICA) is un-der construction in JINR. The NICA goals are providing of colliding beams for studies of hot and dense strongly interacting baryonic matter and spin physics. The NICA complex injection facility consists of four accelerators: Alvarez-type linac LU-20 of light ions up to 5 MeV/u; heavy ion linac HILAC with RFQ and IH DTL sections at energy 3.2 MeV/u; superconducting Booster synchrotron at energy up 578 MeV/u; superconducting synchrotron Nuclotron at gold ion energy 3.85 GeV/u. In the nearest future the old LU-20 will be substituted by a new light ion linac for acceleration of 2<A/z<3 ions up to 7 MeV/u with additional two acceleration sections for protons, first IH section for 13 MeV and the second one - superconducting for 20 MeV. The status of NICA injec-tion facility is under discussion.

	NICA (Nuclotron-based Ion Collider fAcility) is a new accelerator complex designed at the Joint Institute for Nuclear Research (JINR, Dubna, Russia) to study properties of dense baryonic matter. The accelerator complex will consist of three superconducting (SC) rings: the Nuclotron, a booster synchrotron and a two-aperture collider. For the project, it is necessary to produce and test at a helium temperature level (4.5 K) and an operating current of 10 kA of 450 SC magnets. All the magnets contain a cold iron yoke and saddle-shaped superconducting coils made of the hollow NbTi composite SC cable refrigerated by two-phase helium flow at 4.5 K. For this purpose, was created a new factory with a maximum capacity of 12 SC magnets per month. The factory for the production of SC magnets has 8 test-production sections. In the report will show today’s progress in the production of magnets for project, as well as unique cryogenic properties of SC magnets and plans for the production of SC magnets for the NICA project.

	The fast cycling superconducting SIS100 heavy ion accelerator is the designated working horse of the international Facility for Antiproton and Ion Research (FAIR) under construction at GSI in Darmstadt, Germany. The main dipoles will ramp with 4 T/s and with a repetition frequency of 1 Hz up to a maximum magnetic field of 1.9 T. The field gradient of the main quadrupole will reach 27.77 T/m. The integral magnetic field length of the horizontal/vertical steerer and of the chromaticity sextupole corrector magnets will provide 0.403/0.41 m and 0.383 m, respectively. The series production of the high current quadrupoles and of the individually ramped low current corrector magnets was started in 2020 at the JINR in Dubna and is planned to be completed in 2023. We present the technological challenges that have to be solved from production of the first magnets toward a stable and high rate series production with reliably magnet quality as well as the first test results at operation conditions.

	The NICA (Nuclotron-based Ion Collider fAcility) is anew accelerator complex under construction at the the Laboratory of High Energy Physics (LHEP) JINR. The facility includes two injector chains, two existing superconducting synchrotrons Nuclotron and a new Booster, under construction superconducting Collider, consisting of two rings. The lattice of the Booster includes 48 superconducting quadrupole magnets that combined in doublets. Each doublet must be fiducialized to the calculated trajectory of the beam. Alignment of the magnetic axis is necessary for properly install the magnets at the beam trajectory. The vibrating wire technique was applied to obtain the position of the magnetic axis. A new measurement system has been worked out and produced at the LHEP. The magnetic axis positions of the quadrupole doublets are determined at the ambient temperature. Thepaper describes design of the measurement system, measuring procedure and results of the magnetic axis position measurements.

The NICA (Nuclotron-based Ion Collider fAcility) is anew accelerator complex under construction at the the Laboratory of High Energy Physics (LHEP) JINR. The facility includes two injector chains, two existing superconducting synchrotrons Nuclotron and a new Booster, under construction superconducting Collider, consisting of two rings. The lattice of the Booster includes 48 superconducting quadrupole magnets that combined in doublets. Each doublet must be fiducialized to the calculated trajectory of the beam. Alignment of the magnetic axis is necessary for properly install the magnets at the beam trajectory. The vibrating wire technique was applied to obtain the position of the magnetic axis. A new measurement system has been worked out and produced at the LHEP. The magnetic axis positions of the quadrupole doublets are determined at the ambient temperature. Thepaper describes design of the measurement system, measuring procedure and results of the magnetic axis position measurements.

NICA Collider includes 80 dipole two-aperture superconducting magnets. 80 main and 6 reserve magnets were manufactured and tested by specially designed magnetic measurement system. Dipoles were tested at an ambient and operating temperatures. This paper contains the main results of magnetic measurements of the NICA Collider dipoles.
