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.

Issues addressed and main goals of research:
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 set-ups), and the development of the accelerator systems. The project leads to an increase in the operation stability of the accelerators, to 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 to an improvement of the quality of the beams with a simultaneous reduction of power consumption. The project aims at significantly improving 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 major results in the current year:
  • Experiments at the Superheavy Element Factory (SHE Factory) to determine the optimum parameters for the new gas-filled separator of nuclear reaction products DGRFS-2.

  • Extraction of beams of accelerated heavy ions at the SHE Factory. Preparation for experiments on the synthesis of a new element 119.

  • Construction of a pre-separator for radiochemical studies of SHE - a new gas-filled recoil separator DGFRS-3.

  • Experiments at the new ACCULINNA-2 fragment separator (U-400M cyclotron) using beams of light ions with the energies of 30 to 50 MeV/nucleon. Development of the infrastructure of the ACCULINNA-2 fragment separator (RF-kicker).

  • Commissioning of works on upgrading the U-400M cyclotron.

  • Development of the U-400 (U-400R) project that targets the construction of an experimental hall.

  • Implementation of the experimental programme on the synthesis and study of superheavy nuclei and on the spectroscopy of heavy nuclei at the U-400 cyclotron.

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

  • Construction of a new gas-cell-based laser ionization set-up (GALS) for on-line separation of reaction products by selective laser ionization.

  • Development of the high-resolution magnetic analyzer MAVR (equipped with a detecting device) and first experiments with heavy-ion beams. 11

  • Preparation of technical assignments for the manufacture of separate nodes of the gas ion catcher and manufacture order placement.
