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 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. 

Main results expected in 2018:

  • Commissioning of the Factory of superheavy elements (SHE) consisting of: a new experimental building of the Factory equipped with engineering systems, DC-280 cyclotron systems, and a new gas-filled recoil separator DGFRS-2. 

  • Extraction of beams of accelerated heavy ions at the SHE Factory. Conducting of first test experiments on synthesis of isotopes of elements 114 (Fl) and 115 (Mc). 

  • Conducting of first 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 (RF-kicker, zero degree spectrometer). 

  • Conducting of experiments with 6-15 MeV/nucleon ion beams at 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 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. 

  • Finalization of construction of high-resolution magnetic analyzer MAVR. 

  • Design of separate nodes of the gas ion catcher and preparation of construction orders. 

  • Design and construction of a new ECR ion source and hot solid-state catcher with chemical inactive coating of the inner parts of the vacuum chamber of the MASHA separator.
