  1. 99 th session of the JINR Scientific Council Nuclear Physics PAC Dubna, January, 2006

  2. Programme of Nuclear Physics Research for 2006–2008 • The PAC took note of the proposals for the JINR Programme of Nuclear Physics Research for 2006–2008 presented by laboratories, in which the available resources will be concentrated on the most important directions of research Dubna, January, 2006

  3. Bogoliubov Laboratory of Theoretical Physics The main goals • the properties of nuclei near drip lines; • the structure of superheavy nuclei; • the dynamics of nuclear reactions and mechanisms of production of exotic nuclides; • the fundamental properties of exotic few-body nuclear, atomic and molecular systems; • the behavior of nuclear matter and its phase transitions at high temperature and density; • to elaborate new methods of relativistic nuclear physics and apply them to analyse subnuclear and spin effects in few-nucleon systems Recommendation. The PAC approves this programme and recommends adequate fundingof the theme “Nuclear theory” with first priority for 2006. Dubna, January, 2006

  4. Dzhelepov Laboratory of Nuclear Problems The PAC aproves the progress report on the numerous activities at DLNP, grouped in • The efforts in searches for double beta-decay aiming for greatly enlarged lifetime limits are impressive and should be pursued vigorously. • Concerning the Phasotron, the PAC is pleased to note that the consequences of the recent fire accident are being overcome and that the Phasotron operation can be scheduled for the summer of 2006. • It also welcomes an adequate support of the JINR and FLNP directorates for recommissioning this facility. Recommendation. “Investigation of fundamentalinteractions in nuclei at low energies”, “Nucleus and particle interactions at intermediate energies”, and “Development of the JINR Phasotron for fundamental and applied research” should be continued with first priority in 2006. Dubna, January, 2006

  5. Flerov Laboratory of Nuclear Reactions The PAC was pleased to hear the encouraging new results on the synthesis of superheavy nuclei with Z=118. It wishes the Laboratory success in the continuation of these experiments. The programmefor the years 2006–2008 is focused on major research areas: • synthesis of superheavy elements including reaction studies, and investigations of their nuclear and chemical properties, • studies of reaction mechanisms, gamma spectroscopy of the heaviest elements, • the production and structure studies of exotic light radioactive nuclei. Dubna, January, 2006

  6. Recommendations. The PAC approves this programme and acknowledges its scientific merits. The themes “Development and construction of an accelerator complex for producing radioactive ion beams (project DRIBs)”, “Synthesis of new nuclei and study of nuclear properties and heavy-ion reaction mechanisms”, and “Development of the FLNR cyclotron complex for producing intense beams of accelerated ions of stable and radioactive isotopes” should be continued in 2006 with first priority. Adequate funds should be provided. The upgrade of the U400M–U400 accelerator complex is essential for the challenging research programme of FLNR and for maintaining its leadership in the field. The acceleration of low-energy beams at U400M should be realized with particular urgency. These would allow an uninterrupted running of experiments during the modernization of U400. Timely preparation of experimental equipment is an essential prerequisite for the realization of the FLNR research programme. The PAC appreciates the satisfactory running time of the FLNR cyclotrons in 2005. The required beam time of 5500 hrs at U400 and 3500 hrs at U400M should be fully allocated in 2006. Dubna, January, 2006

  7. Frank Laboratory of Neutron Physics The PAC was impressed by the proposed FLNP scientific programme on neutron nuclear physics, containing the following priorities in fundamental research: experiments with polarized neutrons and nuclei, fundamental properties of the neutron, UCN physics, nuclear fission, and nuclear structure. • Recommendation. The PAC approves the FLNP research activity at JINR and external neutron sources, which give valuable scientific results and permit to maintain the high expertise of this Laboratory’s scientists. The theme “Nuclear physics with neutrons” should be continued with first priority in 2006. Dubna, January, 2006

  8. Laboratory of Information Technologies The PAC noted with satisfaction the present status of the networking system at JINR worked out by LIT, and appreciates the future plans for making the communication system more effective. Recommendations. The mathematical support of experimental and theoretical studies at JINR, provided by the Laboratory, should be continued and further strengthened. The PAC recommends continuation of work performed at LIT within the direction “Networks, Computing, Computational Physics” on the themes “Information, computer and network support of JINR’s activity” and “Mathematical support of experimental and theoretical studies conducted by JINR” with first priority in 2006. Dubna, January, 2006

  9. Draft road map in the field of nuclear physicspresented by M. Itkis • The PAC heard with interest the summary of the main lines of research planned by nuclear physics groups in corresponding laboratories for the next three years, and accepts this presentation as an initial step in the road map aimed at a long range of 10–15 years. • The PAC therefore recommends that all JINR nuclear physics groups discuss and formulate in a common effort the strategic lines of research in nuclear physics in 15 years’ perspective. • The PAC also emphasizes that this plan should maintain a vigorous programme in nuclear physics which will exploit the opportunities offered at JINR as a laboratory with world-class expertise in nuclear science Dubna, January, 2006

  10. IREN project The PAC was pleased to hear the FLNP Directorate’s information concerning the successful start-up of dismantling IBR-30 and the recent progress in the creation and adjustment of LINAC components. The PAC agrees with the decision of the JINR Directorate concerning reducing the full-scale IREN project to its first stage (LINAC with a non-multiplying target). Recommendation. The PAC recommends extension of the theme “Construction of the IREN facility (IREN project)” for one year with first priority with the tasks for 2006: the completion of dismantling IBR-30 and complex tests of the accelerator systems. The final goal is to create by the end of 2007 the 1st stage of IREN, including the electron accelerator, the stand for applied research, and the neutron producing target. A work plan with budget assessment and detailed scientific programme, coordinated with FLNR, should be presented by the project management at the next PAC meeting. Dubna, January, 2006

  11. IREN 1st stage parameters Initial data: E=100 MeV, I=2.5 A, dt=100 ns, f=50(150) Hz Dubna, January, 2006

  12. SADproject The PAC heard an exciting status report about the project “Subcritical Assembly at Dubna” (project SAD), and welcomes the plans for creating an international facility at Dubna for addressing important problems of modern nuclear energy production and waste transmutation. The PAC regards SAD as a project establishing closer connection of JINR with the world scientific transmutation community. This project is still in the R&D phase, and the terms of international collaboration and financing should be worked out. Dubna, January, 2006

  13. Recommendations. The PAC encourages collaboration between the SAD project and the Integrated Project EUROTRANS with the support of the International Scientific and Technical Centre (ISTC). A detailed proposal is expected at a forthcoming meeting, specifying also the details of collaboration and the financial resources. For a project of this magnitude, special funds should be sought from national energy agencies. The PAC recommends that the FLNP and DLNP directorates consider the possibility of including SAD in the JINR Topical Plan of Research as a separate theme of first priority. Dubna, January, 2006

  14. Why SAD in Dubna: • Transmutation and ADS is a very attractive path to develop or regain development activities in advanced nuclear technology • For many JINR members countries it is a good chance • WE CAN CREATE A CENTRE OF EXCELLENCE IN TRANSMUTATION RESEARCH IN DUBNA Dubna, January, 2006

  15. European ADS landscape: • MUSE experiment, successully completed • Features: • Zero power, fast neutron spectrum, sodium coolant, MOX fuel • YALINA experiment, in reality the first European neutron generator driven experiment, First phase completed: • Zero power, thermal neutron spectrum, polyethylene moderator, HEU fuel • YALINA experiment, phase 2, Yalina Booster • Zero power, coupled fast-thermal core, lead-polyethylene moderator-coolant, HEU fuel • MegaPie target experiment at PSI • 1 MW liquid Pb-Bi spallation target Dubna, January, 2006

  16.
