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, expansion of the experimental infrastructure of the Laboratory (construction of new physics set-ups), and development of accelerator systems. The project aims at improving the operation stability of accelerators, increasing the intensity and improving the quality of ion beams of stable and radioactive nuclides in the energy range from 5 to 100 MeV/nucleon, while at the same time reducing power consumption. The project objective is to significantly improve the efficiency of experiments on the synthesis of superheavy elements and light nuclei at nucleon drip lines and study of their properties. Moreover, the programme of experiments with beams of radioactive nuclides is anticipated to be expanded.

Expected results in the current year:

Experiments aimed at the synthesis and study of the properties of superheavy elements Fl–Lv at the new gas-filled recoil separator GFS-2 of the Factory of Superheavy Elements (SHE).
Preparation for experiments on the synthesis of elements 119 and 120 in complete fusion reactions with ⁵⁰Ti and ⁵⁴Cr ions.
Development of the pre-separator for radiochemical studies of SHE.
Experiments at the gas-filled recoil separator GFS-3 aimed at the study of the chemical properties of elements 112 and 114.
Completion of the upgrade of the U-400M cyclotron and its commissioning.
Development of the infrastructure of the ACCULINNA-2 fragment separator (RF kicker, tritium target complex).
Implementation of the physics experiments programme at U-400.
Construction of the experimental hall of the U-400R cyclotron.
Preparation for the reconstruction of the U-400 cyclotron (U-400R).
Development of the detector system in the focal plane of the MAVR analyzer and MULTI spectrometer including the 4π-neutron detector and the gamma-detector.
Development of methods for the diagnostics of beams of stable and radioactive nuclides.
Further development of the gas-cell-based laser ionization and separation set-up GALS.
Completion of the assembly of the cryogenic gas ion catcher and the beginning of the adjustment of vacuum and cryogenic systems.
Construction of the DC-140 cyclotron
Preparation of basic engineering design data for a radiochemical laboratory of the first class.
