Main targets of “NICA Complex”: - study of hot and dense baryonic matter - investigation of nucleon spin structure, polarization phenomena - development of accelerator facility for JINR providing intensive beams of relativistic ions from p to Au polarized protons and deuterons with max energy up to √S NN = 11 GeV (Au 79+ ) and =26 GeV (p) - development of infrastructure for applied research Nuclotron Based Ion Collider fAcility - NICA

QCD phase diagram - Prospects for NICA Energy Range of NICA unexplored region of the QCD phase diagram:  Highest net baryonic density  Onset of deconfinement & phase transition  Discovery potential: a) Critical End Point (CEP) b) Chiral Symmetry Restoration  Complementary to the RHIC/BES, FAIR, CERN experimental programs NICA Nuclotron-M RHIC-BES NICA facilities provide unique capabilities for studying a variety of phenomena in a large region of the phase diagram 3

Progress in ion sources B=5.4 Tesla magnetic field reached in a robust regime The commissioning of ESIS started this spring. July-Sept run: Au (54+) ions (~ 5x10^8 ions) generated in a test mode Heavy ion source: Krion-6TeslaSource for polarized particles (SPP) Assembled in this year and commissioning started in June. The goal is to get deuterons per pulse by 2014.

First dipole and quadrupole superconducting (Nuclotron-type) magnets for the NICA booster successfully passed the cryogenic test on the bench. Serial production of the magnets for the booster is scheduled for Cryogenic tests of the model twin aperture dipole and quadrupole magnets for the NICA collider started in this year.

NICA Conventional Facility & Siting (CF&S) International tender is in the final stage: 5 large companies are bidding for the Contract. Approval of the Consortium for NICA construction (3 large companies) for start of the negotiations of Contract is planned for November Signing of the Contract is foreseen in Dec-Jan. July 2013 – NICA TDR had been submitted to the State Expertise (Moscow). 28 October 2013 the State Expertise successfully passed. Allowance for civil construction obtained !

JINR – China Cooperation 19 JINR closely co-operate with Institute of Plasma Physics CAS (ASIPP, Hefei). Superconducting elements for NICA are produced at ASIPP (17 kA current leads). We plan to enlarge collaboration: JINR ready to sign Contracts, China is ready to become NICA member and to provide in- kind contribution starting from this year ! Russian Prime-Minister Dmitry Medvedev and 1 st deputy of RF Minsiter of Science and Education Nataliya Tretyak had visited ASIPP Hefei in frames of his official State visit to China. During tour at ASIPP two mega-projects were presented to him: EAST (China) and NICA (JINR, Dubna). Premier had charged RF Ministry to approve NICA mega-science project as top priority and prepare for signing Bilateral MoU between China, Russia and JINR on the NICA collaboration NICA current leads

6 of them + JINR signed the Protocol 5. The Parties have agreed to inform their Governments about the Meeting on Prospects for Collaboration in the Mega- Science Project “Complex of Superconducting Rings for Heavy Ion Colliding Beams” – the NICA Complex and to express their interest in preparing a corresponding multilateral Agreement and in taking steps towards its approval by their countries Representatives of 13 countries 20

Conclusions  The NICA Complex is well progressing in both fixed target & collider modes  New participants are welcome to collaborate in (2014) & MPD (2017) projects  The 2-nd Int. Point at the Collider is waiting for PROPOSALS ! LoI for SPD is under preparation by International Spin Physics community 21

Thank you for the attention ! Welcome to JINR in Dubna
