Nuclotron-based ion collider facility (NICA) is an international project-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 1·10 27 cm −2 ·s −1 for Au 79+ . Collision experiments with polarized deuterons and protons 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 planned FAIR synchrotron SIS100 has to deliver high intensity beams for the FAIR project at GSI, Darmstadt. This machine will use fast-cycling 4 T/s magnets with a magnetic field up to 2 T. The NICA booster synchrotron, the NICA collider, and the heavy ion synchrotron SIS100 are based on iron-dominated “window frame”—type magnets with a hollow superconductor winding analogous to the Nuclotron magnet. The status on the manufacturing and testing of the NICA magnets and the SIS100 superconducting quadrupole and corrector magnets are discussed.
