	The main activities of Flerov Laboratory of Nuclear Reactions, following its name - are related to fundamental science, but, in parallel, plenty of efforts are paid for practical applications. For the moment continues the works under creating irradiation facility based on the cyclotron DC140 which will be dedicated machine for applied researches in FLNR. The beam transport system will have three experimental beam lines for testing of electronic components (avionics and space electronics) for radiation hardness, for ion-implantation nanotechnology and for radiation materials science. The DC140 cyclotron is intended for acceleration of heavy ions with mass-to-charge ratio A/Z within interval from 5 to 8.25 up to two fixed energies 2.124 and 4.8 MeV per unit mass. The intensity of the accelerated ions will be about 1 pmcA for light ions (A<86) and about 0.1 pmcA for heavier ions (A>132). The following elements are used to extract the beam from the cyclotron: electrostatic deflector, focusing magnetic channel, Permanent Magnet Quadrupole lens and steering magnet. The design of the beam extraction system of DC140 cyclotron are presented in this report.

	The first experiment at the Super Heavy Elements Factory (SHE) was launched at the end of 2020. The result of the experiment with a calcium ion beam and an Americium target is more than 100 events of the synthesis of Moscovium. The last two years have shown good capabilities of the Factory. These results allow us to start preparing for the synthesis of SHE with atomic number >118. For this experiment, we have to use heavier ion beams, such as titanium and chromium. The article describes the method, technique, and last experimental results on the production of metal ion beams such as 48Ca, 48Ti, 52Cr, and 54Cr ion beams at the DC-280 cyclotron from the DECRIS-PM ion source.

	The first beam of 84Kr¹⁴⁺ ions was accelerated in the DC-280 on December 26, 2018 and extracted to the ion transport channel on January 17, 2019. In March 2019, beams of accelerated 84Kr⁺14 ions with intensity of 1.36 pmkA and 12C⁺2 ions with and intensity of 10 pmkA were extracted from the DC-280 to the beam transport channel with energy about 5.8 MeV/nucleon. In 2020-2021 years, beams of 48Ca⁷⁺,10+ ions with intensity up to 10,6 pmkA were accelerated and 7,1 pmkA were extracted from the DC-280 to the beam transport channel with energy about 4,51 - 5,29 MeV/nucleon. In 2021 year, beams of accelerated 52,54Cr¹⁰⁺ ions with intensity up to 2,5 pmkA were extracted from the DC-280 to the beam transport channel with energy about 5,05 MeV/nucleon and beams of 48Ti⁷⁺ with intensity up to 1pmkA and with energy about 4,94 MeV/nucleon The main task of the new accelerator is implementation of the long-term program of researches on the SHE Factory aimed on synthesis of new elements (Z>118) and detailed studying of nuclear- physical and chemical properties of earlier opened 112-118 ones.

	The DC-280 is the high intensity cyclotron for Super Heavy Elements Factory in FLNR JINR. It was designed for production of accelerated ions beam with intensity up 10 pµA to energy in range 4 - 8 MeV/n. The beam power is up 3,5 kW. The diagnostics elements shall be capable of withstanding this power. Moreover such intensity beam required continuous control for avoid of equipment damage. Special diagnostic equipment were designed, manufactured and commissioning. During the design the calculation of thermal loads was made. Some of them were tested before installation on cyclotron. Diagnostic elements used on DC-280 cyclotron are described in this paper. The special Faraday cup was designed for beam cur-rent measurement. The moving inner probe and multylamellar probe are inside the cyclotron. The Scanning two-dimension ionization profile monitor was produced for space distribution analysis of accelerated high intensity beam. Inner Pickup electrode system with special elec-tronic was created for beam phase moving analysis. Time of flight system based on two pick-up electrodes for energy measured was placed in transport channel. These and over diagnostic system were commissioned and tested. The results present in report.
