  The heavy ion synchrotron SIS100 is the main accelerator of the FAIR complex (Facility for Antiproton and Ion Research) in Darmstadt, Germany. Currently the construction site and facility are advancing fast. The series production of the main dipoles was already started in 2017. In parallel, the first two quadrupoles, a chromaticity sextupole and a steerer were built and tested in cooperation between GSI and JINR at the cryogenic test facility in Dubna. We present the operation performance of these two first of series quadrupole units (consisting both of a corrector magnet mechanically and hydraulically combined with a quadrupole). Besides the thermal stability of the fast ramped superconducting magnets special attention is directed to their magnetic field properties. The obtained results provide the basis for starting the series production of all SIS100 quadrupole and corrector magnets in 2018.

  NICA is a new accelerator complex under construction at the Joint Institute for Nuclear Research (JINR) in Dubna, Russia, to study properties of hot and dense baryonic matter. Magnetic system of the NICA collider includes 80 twin-aperture dipole and 86 quadrupole superconducting magnets. The collider twin-aperture magnet is 1.94 m long, 120 mm/70 mm (h/v) aperture with window-frame design similar to the Nuclotron magnet. The measurement of the magnetic field parameters is supported to be conducted for both apertures of each collider magnet. This paper describes magnetic measurements methods and the development of the dedicated system for serial dipole magnets of the NICA collider.

  NICA is a new accelerator collider complex under con-struction at JINR, Dubna. More than 250 superconducting magnets are needed for the NICA booster and collider. The NICA Booster magnetic system includes 48 quadrupole superconducting magnets. The rotating coils probe developed for series magnetic measurements of booster quadrupoles doublets, as well as measuring methods are described. Results of magnetic measurements in cryogenic conditions for 12 doublets are presented and discussed.
