    Year 2017

    Development of the FLNR Accelerator Complex
    and Experimental Setups (DRIBS-III)

    Leaders:    G.G. Gulbekian
       S.N. Dmitriev
       M.G. Itkis
    Scientific leader:   Yu.Ts. Oganessian

    Participating Countries and International Organizations:
    Belgium, Bulgaria, CERN, China, Czech Republic, Egypt, France, Germany, Italy, Kazakhstan, Mongolia, Poland, Romania, Russia, Serbia, Slovakia, South Africa, Ukraine, Uzbekistan, USA.

    Scientific Programme:
    The implementation of the DRIBs-III project that includes the upgrade and development of the FLNR cyclotron complex, the expansion of the experimental infrastructure of the laboratory (construction of new physics setups), and the development of the accelerator systems. The project leads to an increase in the operation stability of the accelerators, an increase in the intensity of the ion beams of stable and radioactive nuclides in the energy range from 5 to 100 MeV/nucleon, and an improvement of the quality of the beams with a simultaneous reduction of power consumption. The project aims to significantly improve the efficiency of experiments on the synthesis of superheavy elements and light nuclei at nucleon drip lines and on the study of their properties. Moreover, the programme of experiments with beams of radioactive nuclides is anticipated to be extended.

    Expected main results in 2017:

    • Completion of the construction and commissioning of a new experimental building of the SHE Factory equipped with engineering systems.

    • Installation of the equipment and DC-280 cyclotron systems in the experimental hall of the SHE Factory. Pre-commissioning works. Extraction of beams of accelerated heavy ions.

    • Construction and commissioning of a gas-filled recoil separator DGFRS-2.

    • Commissioning and conducting of test experiments at the new ACCULINNA-2 fragment separator (U-400M cyclotron) using beams of light ions with energies of 30 to 50 MeV/nucleon. Development of the infrastructure of the fragment separator ACCULINNA-2.

    • Conducting of experiments with 6-15 MeV/nucleon ion beams at the U-400M cyclotron.

    • Production of the intense beams of highly charged ions heavier than Xe using a superconducting ion source and their acceleration in the U-400M cyclotron.

    • Implementation of experiments on the synthesis of new isotopes in the region of superheavy elements at the U-400 cyclotron using actinide targets and on the nuclear spectroscopy of heavy ions.

    • Development of techniques for the synthesis and radiochemical extraction of radionuclides that have great potential for nuclear medicine and are promising as tracers.
      Development of equipment and conducting of experiments with beams at the MT-25 microtron.

    • Development of new methods of beam diagnostics for stable and radioactive nuclides.

    • Construction of a new Gas-cell based Laser-ionization Setup (GALS) for on-line separation of reaction products by selective laser ionization.

    • Development of a two-arm mass-spectrometer MAVR.

    • Design of separate nodes of the gas ion catcher.
