  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, equipment for magnets assembly and tests are installed. Three helium satellite refrigerators with each capacity of 100 W were commissioned 2 of 6 test benches for magnets testing are assembled and commissioned. NICA booster magnets fist cryogenic tests are done. The results are discussed.

  According to the agreement between the Institute of Plasma Physics (IPP) of the Chinese Academy of Sciences in Hefei (China) and Joint Institute for Nuclear Research, Dubna, (Russia), the development of a superconducting isochronous cyclotron for proton therapy SC200 is started. The cyclotron will provide acceleration of protons up to 200 MeV with maximum beam current of 1 μA. We plan to manufacture in China two cyclotrons: one will operate in Hefei cyclotron medical center the other will replace Phasotron in Medico-technical Center JINR Dubna and will be used for further research and development of cancer therapy by protons. Now we present main parameters of cyclotron and simulation results of magnetic, accelerating and extraction systems.

  The physics program and the present status of the project of NICA collider, which is under construction at JINR (Dubna), are presented. The main goal of the project is to provide ion beams for experimental studies of hot and dense strongly interacting baryonic matter and spin physics. The proposed physics program concentrates on the search for possible manifestations of the phase transitions and critical phenomena in the energy region, where the excited matter is produced with maximal achievable net baryon density, and clarification of the origin of nucleon spin. The collider will provide heavy ion collisions in the energy range of √sNN=4/11 GeV at average luminosity of L=1·1027cm−2·s−1 for 197Au79+ nuclei and polarized proton collisions in energy range of √sNN=12/27 GeV at luminosity of L≥1032cm−2·s-1. The key issue of the accelerator complex is application of sophisticated beam accumulation schemes and both stochastic and electron cooling methods. Strong space-charge effects in the collider arise a challenge to its optics and application of novel methods of beam stability maintenance.
