NICA: Required resources from the JINR budget for Dedicated RF funding for NICA

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

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. In its final stage NICA will represent high scientific excellence, pan-European relevance and a socio-economic impact NICA construction already involves Russian and European companies in active works for several years

Good visibility creates interest of new potential users of the facility. We anticipate increasing of the user base from ~ users now to more than 1500, when all facilities are constructed and fully operational. 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. The requirements and procedure how to use the facility - regulated by JINR rules of project consideration and approval: Proposal for some megascience rules:

 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; International cooperation  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.

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. 08 Aug’13: Representatives of 13 countries 08 Aug’13: Representatives of 13 countries, 6 signed (Belarus, Bulgaria, Germany, Kazakhstan, RF, Ukraine).

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  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 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.
