	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. In 2021, the main its 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. Basing on FLNR long term experience in these fields and aiming to improve the instrumentation, the Flerov laboratory of nuclear reactions starts the new project - the dedicated facility for applied science on the basis of the new heavy ion cyclotron DC-140. Following the user¿s requirements, DC140 will be the multi-particle, double - energy machine, capable with light and heavy ions up to bismuth (2.1 and 4.8 MeV/u). The "ion cocktail" mode will be one of the significant parameters of the new cyclotron. The last year’s efforts in the field of cyclotron practical applications in FLNR and general overview of the DC 140 project - the new FLNR facility for applied science, will be presented.

	Permanent magnet (PM) multipoles in some cases are good candidates in accelerator applications for beam transportation and focusing. The PM quadrupole will be utilized in the DC140 cyclotron which is under construction in JINR. A passive magnetic channel and a PM quad will be used for the compensation of horizontal defocusing in the high and low field regions, respectively. The quad is designed as a set of identical PMs rigidly fixed in a non-magnetic housing and capable to generate a a 8.1 T/m gradient field in the 64x25 mm aperture and 29.926 cm effective length. The error of linear approximation should be 1% or less. A special study was accomplished to define the PM specification reasoning from the demand for desired field strength, simple geometry, minimized nomenclature, and commercial availability. The quad design was selected with the use a 2D analytical model and then optimized in iterative 3D FE simulations with realistic PM shape and magnetic characteristics in mind. The resultant concept is the quad formed with 6 coaxial sections each 5cm in width. Every section has 26 identical PM bricks with the dimensions 11mmx11mmx50mm and different orientations. The PM bricks have remanent induction of 1.185 T and magnetic susceptibility of 0.1. Temperature characteristics and expected lifetime were also analysed. From the results obtained, candidate PM materials were proposed and mechanical and magnetic precision were recommended.

	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.
