  Nuclotron-based Ion Collider fAcility (NICA) is the new accelerator complex being constructed in Joint Institute for Nuclear Research. General goal of the project is to provide experimental study of hot and dense strongly interacting QCD matter. The development of NICA injection complex is actively performed. Construction of new 3.2 MeV/u heavy-ion linear accelerator (HILac) is now under way in Germany. Construction of booster has been started. In this report the present status of the NICA accelerator complex are presented.

  The upgrade of the existing heavy ion synchrotron SIS18 as booster for the FAIR synchrotron SIS100 has been partly completed. With the achieved technical status, a major increase of the accelerated number of heavy ions could be reached. This progress especially demonstrates the feasibilty of acceleration of medium charge state heavy ions with high intensity and and the succesfull control of dynamic vaccuum effects and correlated charge exchange loss. Two further upgrade measures, the installation of additional MA acceleration cavities and the exchange of the main dipole power converter are in progress. For the FAIR synchrotron SIS100 all major components with long production times have been ordered. With several pre-series components, outstanding technical developments have been completed and the readiness for series production reached. The technical project status will be summarized.

  NICA is a new accelerator collider complex presently under construction at Joint Institute for Nuclear Research (JINR) in Dubna. More than 250 superconducting magnets need for the NICA booster and collider. These magnets will be assembled and tested at the new test facility in the Laboratory of High Energy Physics JINR. The first phase of the system for magnetic measurements was commissioned in late 2013. A method of measuring the quality of the magnetic field in the aperture of the curved dipole magnet for the booster synchrotron is described. First results of magnetic measurements are presented and discussed. Commissioning of equipment for magnetic measurements in the aperture of quadrupole magnets for the NICA booster is close to completion.

  The NICA/MPD project has been started at the Joint Institute for Nuclear Research (JINR) in Dubna in 2007. The NICA accelerator complex will consist of two injector chains, the new 600 MeV/u superconducting (SC) booster synchrotron, the existing SC synchrotron Nuclotron, and the new SC collider having two rings each of 503 m in circumference. The building construction of the new test facility for simultaneous cryogenic testing of the SC magnets on 6 benches is completed at the Laboratory of High Energy Physics. Premises with an area of 2600 m2 were prepared to install the equipment. The 15 kA, 25 V pulse power supply, the helium satellite refrigerator with capacity of 100 W were commissioned first bench for magnets testing is now under assembling. First magnets cryogenic tests are planned on July. Start of the serial production of the SC magnets for the booster synchrotron is planned for the end of 2014.

  NICA (Nuclotron-based Ion Collider fAcility), presently under construction at JINR, will be, upon its completion, among the most advanced research instruments of the physics community. The facility is aimed at providing collider experiments with heavy ions up to uranium (gold at the beginning stage) with a centre of mass energy up to 11 GeV/u and an average luminosity up to 1027 cm-2 s−1. The NICA cryogenics includes a large number of technical ideas and solutions never used before. The most significant of these solutions are the fast cycling superconducting magnets, cooling by the two-phase helium flow, an unusually short period of time for cool down till the operating temperature, parallel connection of cooling channels of the magnets, «wet» turbo expanders, screw compressors with the outlet pressure of more than 25 bars and jet pumps for liquid helium. These technical solutions allow one to construct an efficient and reliable cryogenic system of the NICA complex.
