  13. NICA schedule • The decommissioning is foreseen after 2040

  14. NICA: Required resources from the JINR budget for 2017-2023 Dedicated RF funding for NICA

  15. What NEXT? … Prospects for NICA at 20 years Horizon - Experiments on the observation of spontaneous electron–positron pair creation in supercritical Coulomb fields (new 2 compact SC rings with merging bare Uranium beams). - Mass-spectroscopy of radioactive heavy ion beams in isochronous mode (using booster or collider ring) + measurement of nuclei PDF with colliding/merging electron beam (up to 1 GeV). - Accelerator physics R&D in: - SC linear injector for protons (MW beam as a goal) - high-field magnets - up to 5T - high brightness beams (Extrahigh luminosity mode) - Detector R&D in: - silicon trackers - large SC magnets and solenoids using HTSC

  16. In its final stage NICA will represent high scientific excellence, pan-European relevance and a socio-economic impact • since the NICA will be the only facility providing • heavy ion collisions at the collider mode • in the energy range of maximum baryonic density; • collisions of protons & deuterons with all combinations of • transversal and longitudinal polarizations; • variety of extracted heavy ion beams • for applied researches. NICA construction already involves Russian and European companies in active works for several years

  17. Proposal for some megascience rules: The main incentive for engaging of new users will be a unique nomenclature of ion and neutron beams and a scientific infrastructure created at the JINR, Dubna, RF. Good visibility creates interest of new potential users of the facility. The requirements and procedure how to use the facility - regulated by JINR rules of project consideration and approval: http://www.jinr.ru/section.asp?sd_id=220&language=eng We anticipate increasing of the user base from ~ 400-450 users now to more than 1500, when all facilities are constructed and fully operational.

  18. International cooperation • The wide cooperation has been established for • the development of the NICA accelerator and detector complexes, • and for the theoretical support. • This cooperation will be expanded taking into account • the growing experimental collaborations; • The inclusion of the NICA complex and other Russian megascience projects to the ESFRI and BRICS RI Road Maps will give a boost in attracting scientists all over the world for participation in the our project; • The development of the legislative base for international collaborations around Russian megaprojects has been started. NICA – is ideal example of existing RI; • The development of proper social infrastructure is required to give new attraction to Russian megaprojects. State programs could be a good support.

  19. European commission on Russian mega-science projects (May-Dec 2013) The fact that NICA/JINR are part of the EU research infrastructures landscape has already been recognized by ESFRI. The Expert Group (EG) recommends that the NICA project be fully taken into account in the forthcoming discussions on the next update of the ESFRI Roadmap. The EG encourages JINR to continue actively develop new and extended cooperation with potential European partner institutions. The exceptional opportunities available in Dubna to young scientists and engineers should be more widely promoted. HORIZON –2020 ESFRI RoadMap Update 2016 BRICS global RI 08 Aug’13: Representatives of 13 countries, 6 signed (Belarus, Bulgaria, Germany, Kazakhstan, RF, Ukraine). China and South Africa – are ready to join. 08 Aug’13: Representatives of 13 countries Germany (BMBF, GSI) – to the Test Facility for SC magnets and STS, MoU China (ASIPP) – to the HTSC current leads, SC magnets, vacuum systems, MoU USA (FNAL) – to the NICA collider stochastic and electron cooling systems, MoU CERN – to the BM@N and MPD elements (drift chambers, MM systems…, , MoU Rep. of South Africa – cryostats, diagnostics for SC ion source, cryogenics , MoU

  20. EU-Russia Joint Cooperation Committee S&T (JCCST) 19 June 2015, Brussels, European Commission, Directorate-General for Research & Innovation. NICA – is in the Priority List for EU The Nuclear Physics Division Board of the EPS at its 70th Meeting (Leuven, Belgium, Oct 15-16, 2015) has accepted the JINR suggestion to host the 72nd Board Meeting (Sept.28-30, 2016) at JINR, Dubna. This EPS NPD Board decision is mainly motivated by its interest in visiting the old and new JINR flagship facilities (IBR-2M, DRIBs and NICA) to see their status and current development as well as to discuss their prospect collaboration with other EU scientific research infrastructures. • Experience with H2020 and Targeted Programmes • Collaboration in thematic priority areas • Russian National Contact Points for Horizon 2020 • ERA-NET.RUS Plus and thematic ERA-Nets • Large-scale facilities / Research infrastructures • Multilateral initiatives

  21. JINR-Brazil Forum, 15-19 June 2015. Ambassador of Brazil to Russia. JINR-South Africa Forum, September 2015 16 Sept. 2014 - visit of 26 researchers and science officers

  22. Meeting of the BRICS Funding Agencies in science and technology Moscow, Ministry of Education and Science, July’15 Decision to organize a coordination between BRIKS countries on Large Research Infrastructure (megascience projects): several in China (HIAF, ASIPP, JUNO, etc.), South Africa (SKA), India (supercomputer center, SR sources), Brazil (SR source, space center), Russia (NICA, PIK, Ignitor, SR4, SuperC-tau, XCELS). JINR – chair in the WG, NICA – submitted to BRICS development Bank

  23. China-NICA- JINR Cooperation Scientific program of the NICA had been recognized as highly perspective for participation of China centers. Sides agreed to perform required agreement procedures to prepare signature of the Memorandum on the Governmental level providing China participation in the NICA megaproject

  24. NICA International collaboration Megaprojects: Workshop in Dubna (Italy, Germany, France, China, Egypt, SAR, RF) JINR-France (IN2P3) MoU
