	The NICA Collider is a new superconducting facility that has two storage rings, each of about 503 m in circumference, which is under construction at the Joint Institute for Nuclear Research, Dubna, Russia. The influence of the fringe fields and misalignments of the lattice magnets, the field imperfections and natural chromaticity should be corrected by the magnetic field correction system. The layout and technical specification of the magnetic field correction system, the main parameters, arrangements and the field calculations and measurement results of the corrector magnets are presented. The results of dynamic aperture calculation at working energies are shown.

	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.
