© 27th Russian Particle Accelerator Conference, RuPAC 2021. All rights reserved.An accelerating structure with radio frequency quadrupole (RFQ) [1] focusing is considered. The RFQ is capable of providing bunching and acceleration of ion beams from H+ to O5+ to energies of the order of 1 MeV/nucleon, with an A/Z ratio from 1 to 3.2. The proton current reaches 2 mA, and the ion current reaches 1 mA. The calculation of the dynamics of ions has been carried out. An electrodynamic model of a four-vane RFQ with magnetic coupling windows has been created. The dependence of the operating frequency of the cavity on its geometric parameters is found. The geometry of the magnetic coupling windows, which provides the optimal mode separation, is determined. Various types of cavity shells are considered and the corresponding electrodynamic characteristics (EDC) are obtained. The influence of additional frequency tuning elements (plungers and "spacers" of frequency tuning) on the EDC is investigated. As a result, an optimized electrodynamic model of the accelerating structure is obtained.
