  3. Heavy ion Physics – Basic Facilities • The basic role in realization of the plan of researches is associated with creation of accelerator complex DRIBs-III. • The purpose of the project is expansion of a set of accelerated ions, both of stable, and radioactive isotopes, essential increase of intensity and quality of beams. • Realization of project DRIBs-III provides: • a new experimental hall, • development of new generation experimental set-ups, • completion of modernization of cyclotrons U400 and U400М, • new high-intensity universal accelerator of heavy ions.

  4. Heavy ion Physics – Basic Facilities 1. Modernization of accelerator U400M. The basic purposes of the modernization started in 2007 are: increase of intensity of light ion beams by a factor of 4 – 5, increase of the maximal energy of light ions up to 100 MeV/A and, acceleration of lowered (6 – 15 MeV/A) energy ions, increase of stability of parameters of beams, extraction of beams in the second direction. 2. Modernization of accelerator U400. The basic purposes of planned in 2010 – 2011 modernization of the accelerator are: improvement of quality and intensity of stable and radioactive beams, providing of a smooth variation of energy of ions in the range 0.8 – 25 MeV/A, decrease in the consumption of rare isotopes, decrease in power consumption by a factor of 3 – 4. 3. Development of highly effective multi charged ion sources

  5. Heavy ion Physics – Basic Facilities New FLNR experimental hall The small area of the existing U400 experimental hall (nearby 150 м2) does not allow to place new experimental set-ups and leads to significant losses of time due to impossibility to work on another set-up if an experiment is running on one of them. For the radical solving of this problem construction of a new experimental hall having the area 2500 м2 is planned. It will be used for work with beams of radioactive and exotic nuclei using new experimental set-ups, including those from other research centers.

  7. Heavy ion Physics – Basic Facilities New high-intensity accelerator of heavy ions Principal cause demanding creation of the new accelerator, is the impossibility of essential increase in intensity of beams of accelerated ions on existing accelerators (even after their modernization) owing to problems with injection into and extraction of ions from the accelerator. It should have an opportunity of stand-alone operation; work as the driver accelerator for producing ions of radioactive isotopes, and as postaccelerator in DRIBs-III complex; produced beams should be transported to available experimental halls. It is necessary to provide acceleration of ions from carbon up to uranium up to energy 5 – 10 MeV/A with stepwise and smooth variation. For ions with masses A<100 the beam intensity should be not below 5·1013/s.

  11. Experiments on FLNR accelerators 1. Synthesis and studying of properties of superheavy elements In 2010-2016 efforts will be concentrated on further more detailed studying of already opened isotopes of superheavy elements, and also on search of new methods of synthesis of heavier elements. Planned experiments will be aimed at synthesis of nuclei with Z=110–120 in reactions between 232Th, 236,238U, 237Np, 242,244Pu, 241,243Am, 246,247,248Cm, 249Вк and 249Cf with 36S, 48Ca, 50Ti, 58Fe and 64Ni. The significant attention will be given to synthesis of an element with Z=117. 2. Characteristics of the spontaneous and induced nuclear fission Mechanisms of formation and decay of heavy and superheavy nuclei in reactions with heavy ions will be studied on CORSET (+ DEMON +HENDES) and FOBOS set-ups which allow to study mass-energy distributions of fission fragments, preequilibrium, pre- and post scission neutrons, and also multiplicities and energy of γ-quanta

  12. Experiments on FLNR accelerators 3. Chemical properties and identification of superheavy elements For the comparative studying of chemical properties of superheavy elements and their light homologues compounds methods of gas phase termohromatography, and also methods of an ionic exchange and extraction from solutions are applied. 4. Mass spectrometry of isotopes of superheavy elements For precision measurement of masses and studying of physical and chemical properties of these elements separator MASHA at the beam of the modernized cyclotron У400М will be used. In experiments with the use of a plasma ion source for isotopes of Kr, Xe and Hg at the test bench the mass resolution Δm/m≈3∙10-4 has been reached. The «MASHA» set-up considerably surpasses known similar devices by efficiency of separation of superheavy atoms and completeness of the information on characteristics of their decay.

  13. 5. Nuclear spectroscopy of isotopes of heavy and transfermium elements Together with IN2P3 (France) will proceed the realization of the project GABRIELA on α-, β- and γ-spectroscopy of transfermium isotopes with the use of the separator VASSILISSA. 6. Mechanisms of reactions with stable and radioactive nuclei Experiments with beams of radioactive isotopes will be carried out on ACCULINA set-up. Secondary beams of ions 6,8He, 9,11Li, 12,14Be, 8B with energy in the range 25-35 MeV/A are produced by irradiation of targets with primary beams of 7Li, 11B, 13C, 15N and 18O ions, generated by the cyclotron U400М. For ions 6He and 8He with the energy 25 Mev/A intensities of 1.5106 and 7103 particles/s were reached. Mechanisms a nucleon-nuclear interactions at energy in the near to Fermi's domain are studied on a fragment separator COMBAS allowing also to produce secondary beams of neutron rich nuclei with 2≤ Z≤11

  44. Concluding remarks • Presented draft planning is based on the current vision of the JINR budget for years 2010-2016, proposed to the Committee of Plenipotentiaries by JINR Directorate and based on the constantly increasing contributions of JINR’s Member States year by year. Security of the budget is of primary importance here. • Planed distribution of funds between topics and their financial profiles have to be made consistent with overall budget limitations. • It is clear that timely execution of presented tasks requires further concentration of human and material resources. • Fresh young personnel from Member States is highly welcome.
