  Basic goal of the planned NICA facility at JINR is focused on the studying of heavy ion collisions over the energy range √s ~ 4…11 GeV/u. Capabilities of the proposed scheme were carefully analyzed in this case and reaching of the desired average luminosity, L = 1·1027 cm-2 s−1 for gold-gold collisions at √s = 9 GeV/u, have been confirmed. The other important NICA research domain is the experiments with polarized proton beams at the highest possible energy, the highest luminosity and polarization degree as well. The main aim is to provide √s ~ 25 GeV and L ~ 1·1031 cm-2 s−1. The unsolved aspects of the problem are discussed, possible solutions are analyzed and necessary modifications of the NICA scheme are considered as well.

  The Nuclotron upgrade – the Nuclotron-M project, which had been started in 2007, involved the modernization of almost all of the accelerator systems, using beam time during seven runs devoted to testing newly installed equipment. Following the project goals, in March 2010 Xe ions were accelerated to about 1.5 GeV/u. In December 2010, the stable and safe operation of the magnetic system was achieved with a main field of 2 T. The successful completion of the project paves the way for further development of the Nuclotron-based Ion Collider fAcility (NICA).
