  Status of JINR FLNR cyclotrons and plans of their modernization together with plans on creation of new facilities will be reported. At present, three cyclotrons: U400, U400M and IC100 and MT-25 microtron are under operation at the JINR FLNR. U400 and U400M are the basic FLNR facilities that both are under operation is about 12000 hours per year. The U400 (pole diameter of D=4 m) was designed to accelerate ions from B to Bi up to 19 MeV/u. U400 reconstruction is planned. The U400M cyclotron (D=4 m) is used to accelerate ions from Li to Xe up to 60 MeV/u. U400M modernization is planned. The IC100 accelerator (D=1m) is used for applied researches with Ar, Kr and Xe ions at energy of 1.2 MeV/u. Creation of the dedicated DC-130 cyclotron (D=2m) with ion energies of 4.5 and 2 MeV/u is planned on the base of U200 cyclotron. The Super Heavy Element Factory (SHE factory) is the new FLNR JINR project. The DC-280 cyclotron (D=4 m) is the basic facility of the SHE factory, which will accelerate ions with energies 4 - 8 MeV/u cyclotron at intensities up to 10 pmkA for ion masses over A=50. The main systems of the DC-280 were assembled and tested, the cyclotron is preparing for commissioning.

  The synthesis of heavy and the heaviest elements and the study of their nuclear and chemical properties are of highest priority in the basic research programme of the Flerov Laboratory of Nuclear Reactions. The synthesis of super heavy elements (SHE) with atomic numbers 113-118 has been achieved in the 48Ca-induced reactions. The International Unions of pure and applied physics (IUPAP) and chemistry (IUPAC) recognized the priority of Dubna in the discovery of elements 114 ’ 118. The seventh period of the Periodic Table has been completed. In accordance with the development program, the first in the world Super heavy Element Factory is being built at the Laboratory on the basis of the new DC280 cyclotron which has to provide intensities up to 10 pμA for ions with atomic masses over 50. The main task of the Factory is the synthesis of new chemical elements with atomic numbers 119 and higher, as well as a detailed study of the nuclear and chemical properties of previously discovered superheavy elements. The Factory will be equipped with target materials, new separators and detectors for the study of the nuclear, atomic and chemical properties of the new elements.
