  13. Since the construction of a neutron source takes significant time, the PAC finds it timely to consider a proposal for a new facility at the moment. • At the same time, the PAC notes the urgency of addressing a number of issues such as • mobilizing a large scientific community for the development of a new source; • considering complementarity and competitiveness with other neutron sources to be available after 2032 both in Russia and elsewhere in Europe; • clarifying ideas on the instruments and novel technologies to be usedat the new source; • identifying the relevant user community both at JINR and outside.

  14. Recommendations Recommendation 1.The PAC believes that a comprehensive analysis of approaches to the idea of constructing a new neutron source at JINR in place of the IBR-2 reactor after the completion of its operation after 2032 is an important and urgent task, and recommends that the FLNP Directorate start preparation of a proposal for considering the development of a new neutron facility to be presented at the next meeting of this PAC. Recommendation 2. The PAC also recommends that a proposal for the development of a new neutron facility be submitted to the Committee for Long-Term Strategy Planning being currently established at JINR.

  15. IBR-2 scientific and technologicalreview for 2016 D. Kozlenko • The PAC was informed about the main scientific results in the field of condensed matter research and instrumentation developments at the IBR-2 facility obtained in 2016. • The PAC appreciates the high scientific level of the results achieved at IBR-2 instruments and their interdisciplinary character. The upgrade of the IBR-2 instrumentation will increase the quality and level of forthcoming research, extend research areas and provide more attractive conditions for the IBR-2 user community.

  16. The priority directions of scientific research • Physics and chemistry of novel functional materials; • Physics of nanosystems and nanoscale phenomena; • Physics and Chemistry of Complex Liquids and Polymers; • Molecular Biology and Pharmacology; • Materials and Engineering Sciences.

  19. Recommendations on themes and projects Methods, Algorithms and Software for Modeling Physical Systems, Mathematical Processing and Analysis of Experimental Data Gh. Adam The scientific merits of the theme are determined by carrying out advanced research in the field of computational mathematics and computational physics aimed at the development of new mathematical methods, algorithms, and software for addressing the various topics of JINR experimental and theoretical studies by using the newest computational tools, primarily the heterogeneous cluster HybriLIT.

  28. General discussion • The PAC emphasized the necessity to have a pool of external experts to evaluate themes and projects in related fields that are not directly focused on condensed matter physics issues but addressed to this PAC. • The PAC also discussed a possibility of inclusion of its one or two members in the Committee for Long-Term Strategy Planning being currently established at the Institute. • The PAC endorsed the final draft of the Regulation for the JINR Programme Advisory Committees to be approved at the next session of the Scientific Council in February 2017. • The PAC also discussed the guidelines for the preparation of projects and themes and their evaluation by the PACs. It was noted that the general items of these guidelines were also accepted by two other PACs — for Particle Physics and Nuclear Physics.

  29.
