With the emergence of the FLASH irradiation method in proton therapy, the need for high-current accelerators has grown significantly. Addressing this demand, the Joint Institute for Nuclear Research (JINR) has initiated the development of the MSC230, a compact isochronous cyclotron designed to produce high-intensity proton beams at 230 MeV for advanced biomedical research. Currently, the technical design of the cyclotron is in progress at D. V. Efremov Institute of Electrophysical Apparatus. Modifications during this phase often necessitate additional calculations, resulting in updates to the magnetic field configuration and beam dynamics. This article details the design methodologies and computational tools employed in the MSC230 project.
