The isochronous cyclotron DC-280 is intended to accelerate the ion beams with A/Z from 4 to 7 up to the energy 8 – 4 MeV/nucleon. The wide range of the magnetic field levels from 0.64T till 1.32T allows to make a smooth variation of the beam energy over the range ±50% from nominal. For operational optimization of the magnetic field the 11 radial and 4 pairs of harmonic correcting coils are used. The numerical formation of the magnetic field is carried out. The problems and solutions of DC-280 magnetic field design are described.

In the Laboratory of nuclear reactions JINR dedicated accelerator complex on the basis of the heavy ion cyclotron DC110 for the industrial track membrane production has been developed and created. The isochronous cyclotron DC110 accelerates the ions Ar, Kr and Xe with a fixed energy of 2.5 MeV/nucleon and intensity of 10^-15 mkA. The cyclotron is equipped with ECR ion source - DECRIS-5 (18 GHz) and axial injection system. The pole diameter of the magnet is 2 m. Isochronous magnetic field formed by shimming sectors on the level of 1.67 T. Accelerated ions 40Ar⁶⁺, 86Kr¹³⁺, 132Xe²⁰⁺ have close mass-to-charge ratio, which allows changing particles without changing the operation mode of the cyclotron. Accelerator complex DC-10 is capable of producing up to 2 million square meters of track membranes per the year.

The project of the high-voltage (HV) axial injection for the DC-280 cyclotron which is being created at the FLNR JINR is presented. The injection system will consists of a Permanent Magnet ECR ion source and a Superconducting ECR ion source, beam analyzing magnets, focusing solenoids, beam choppers, a polyharmonic buncher, 75 kV DC accelerating tubes, a commutating electrostatic deflector and a spiral inflector. One part of the injection system is situated on the HV platform, another part is on the grounded yoke of the DC-280 magnet. The injection system will allow one to inject efficiently ions of elements from Helium to Uranium with the atomic mass to charge ratio in the range of 4-7.5 providing acceleration of ion currents with intensity more than 10 pmkA.

The design of two magnets of the cyclotron DC280 is presented. The magnets are the parts of injection and extraction systems the cyclotron. The design is based on three-dimensional calculation of the magnet field carried out by using OPERA 3D program code. The influence of the magnetic fields nonlinearities on ion beam dynamics is analyzed.

To date, Warsaw U200P cyclotron exploited a mirror inflector to feed heavy ions extracted from ECR ion source (10 GHz, 11 kV) to the central region of the cyclotron. However, in such configuration very low transmission was reachable after many optimizations. Additionally, the new ECR ion source (14,5 GHz, 14-24 kV) was installed, which offers energies far exceeding capabilities of the currently operated inflector and central region. To avoid these obstacles, we have developed a spiral inflector and redesigned central region of the cyclotron. It was a very challenging task, bearing in mind limited volume of central region in our compact machine, to carve these elements suitably for decent versatility of ion beams offered by Warsaw cyclotron. This project was executed in the collaboration with FLNR in Dubna, Russia. The cyclotron equipped with the new central region works in the "constant orbit" regime. Here we present the results of both computational simulations and measurements of the beam transmission in upgraded central region.
