Dubna scientific medicine center is under development since 1967 on the base of the proton beam of LNP JINR Phazotron. Proton beam with energy Ер~170 MeV and intensity I~0.1 mkA is used for patients irradiation. Proposal of creating of the cyclotron with the same beam characteristics was reported earlier at the conferences RUPAC04, ICAA05 and printed in different magazines. The development of this project was considered in this paper.

The ability of optimal combination of the magnet yoke, HF and extraction systems of the cyclotron taking into account the dynamics of the proton beam in calculated magnetic and accelerating field is under discussion.

The compact isochronous cyclotron is considered as a source of 1.75 MeV protons for the detection of explosives using gamma ray resonant absorption technique. Given the marginal request for the beam intensity and quality H¯ ions were selected for acceleration in the cyclotron aiming at the high efficiency extraction by electrostatic deflector. The tracking calculations were performed by the CBDA code. The electric and magnetic field maps were obtained by the TOSCA/OPERA3D and MERMAID codes. Internal and external injection regimes were tried to select from. The space charge effects of the ions were taken into account in the calculations. The main criteria, imposed in selecting of the operational parameters, were good centering, as high as possible energy gain of the ions in the accelerating gaps, the maximal particles transmission through the machine and the best possible beam quality at the final energy. The overall performance of the facility was optimized by adjusting the corresponding parameters of the cyclotron. Simulation of the interface between the cyclotron and the storage ring was performed in order to provide the required intensity and beam quality for injection to the storage ring.
