  Flerov Laboratory of Nuclear Reaction of Joint Institute for Nuclear Research carries out the works under creating FLNR JINR Irradiation Facility based on the cyclotron DC140. The facility is intended for SEE testing of microchip, for production of track membranes and for solving of applied physics problems. The main systems of DC140 are based on the DC72 cyclotron ones that now are under reconstruction. The DC140 cyclotron is intended for acceleration of heavy ions with mass-to-charge ratio A/Z within interval from 5 to 5.5 up to two fixed energies 2.136 and 4.8 MeV per unit mass. The intensity of the accelerated ions will be about 1 pµAmps for light ions (A<86) and about 0.1 pµAmps for heavier ions (A>132). The injection into cyclotron will be realized from the external room temperature 18 GHz ECR ion source. The simulation of the axial injection system of the cyclotron is presented in this report.

  The DC280 cyclotron is the new accelerator of FLNR Super Heavy Elements Factory. It was commissioned in the beginning of 2019. DC280 is intended for production of high intensity, up to 10 pmkA, beams of heavy ions with mass to charge ratio A/Z= 4 - 7. The wide range of accelerated ions from helium to uranium and smooth variation of extracted beam energy in the range W= 4 - 8 MeV/n are provided by varying of level of main magnetic field from 0.64 T till 1.32 T. The DC280 magnetic field was formed in a good conformity with results of computer modeling. In spite of commissioning of cyclotron still is in progress, the first experiments gave the intensity 1.35 pmkA of 84Kr14+ and 10 pmkA of 12C2+. At the present work the results of calculations, magnetic field measurements and first experiments are presented.

  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 SHE Factory was built at the Laboratory on the basis of the new DC280 cyclotron which was commissioned in 2019. DC-280 has to provide intensities up to 10 pmkA 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 are being equipped with target materials, new separators and detectors for the study of the nuclear, atomic and chemical properties of the new elements.

  Space radiation is the main factor limiting the operation time of the onboard equipment of the spacecraft due to the radiation effects occurring in the electronic components. With a decrease in the size of semiconductor structures, the sensitivity to the effects of individual nuclear particles increases and hitting one such particle can cause an upset or even failure of a component or system as a whole. Since the phenomenon occurs due to the impact of a separate particle, these radiation effects are called Single Event Effects (SEE). To be sure that the electronic component is operational in space, ground tests are necessary. SEE tests are carried out on test facilities that allow accelerating heavy ions from C to Bi to energies from 3 to a few dozen MeV/A. Cyclotrons are best suited for this purpose. In this paper, the installations created by request of ISDE based on the cyclotrons of FLNR JINR are described.

  The main activities of FLNR, following its name – are related to fundamental science, but, in parallel, plenty of efforts are paid for practical applications. Certain amount of beam time every year is spent for applied science experiments on FLNR accelerator complex. The main directions are the production of the heterogeneousμ- and nano-structured materials; testing of electronic components (avionics and space electronics) for radiation hardness; ion-implantation nanotechnology and radiation materials science. Status of all these activities, its modern trends and needs will be reported. Basing on FLNR long term experience in these fields and aiming to improve the instrumentation for users, FLNR accelerator department announce the design study for a new cyclotron, DC140, which will be dedicated machine for applied researches in FLNR. Following the users requirements DC140 should accelerate the heavy ions with mass-to-charge ratio A/Z of the range from 5 to 8 up to fixed energies 2 and 4.8 MeV per unit mass. The first outlook of DC140 parameters, its features, layout of its casemate and general overview of the new FLNR facility for applied science will be presented.
