OPTIMIZATION OF THE DC-60 ACCELERATOR PARAMETERS FOR IRRADIATION OF PET FILMS WITH HEAVY Kr IONS

This paper discusses the setup and optimization of the DC-60 cyclotron operating mode for irradiating polyethylene terephthalate (PET) films with heavy krypton ions to create track membranes. The stages of accelerator tuning are described, including calculations of acceleration parameters and the adjustment of the radio frequency (RF) system for krypton plasma generation. Key parameters are considered, such as magnet current, inflector and deflector voltages, and beam characteristics at the accelerator output. Special attention is given to the beam transport and focusing system, and the optimization of irradiation conditions to ensure the required accuracy and reproducibility of experiments. The results obtained are important for the further development of ion-track modification methods for polymer materials and their application in various technological and commercial fields.
