  Flerov Laboratory of Nuclear Reaction of Joint Institute for Nuclear Research carries out the works under creating of 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 2.124 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 designed RF-system of the DC-72 cyclotron with a half-wave cavity is not suitable due to the big vertical size. For this reason, a new quarter-wave RF-system was developed for the DC140 cyclotron project. The results of calculating the parameters of the new RF-system are given in this work.

  U400M isochronous cyclotron was created on the base of U300 classic cyclotron and is under operation at FLNR, JINR since 1996. At the present time the cyclotron electromagnet with 4 meter pole diameter needs a reconstruction that includes a replacement of magnet main coil, corrections of the magnetic field at the central region and at the extraction radius. For measurements and shimming of cyclotron magnetic field the automatic mapping system, based on 14 Hall probes, will be created.

The system based on four main elements - electrostatic deflector, focusing magnetic channel, Permanent Magnet Quadrupole lens and steering magnet is used in the DC140 cyclotron for extraction of the accelerated beam. The design and simulation of the beam extraction system from the DC140 cyclotron are presented in this report.

  The DC280 is the high current cyclotron with design beam intensities up to 10 pµA for ions with energy from 4 to 8 MeV/nucleon. It was developed and created at the FLNR JINR. The first was extracted from the cyclotron on January 17, 2019. Experiments on acceleration of 12C, 40Ar, 48Ca, 48Ti, 52Cr and 84Kr beams production were carried out. The following intensities of accelerated beam have been achieved: 10 pµA for 12C+2; 9,2 pµA for 40Ar+7; 7,1 pµA for 48Ca+10; 1,0 pµA for 48Ti+10; 2,4 pµA for 52Cr+10 and 1.43 pµA for 84Kr+14;. The accelerator has worked more than 9000 hours. The work of accelerator was stable and high efficiency. The total acceleration efficiency from ion source to transport channel was about 46%.
