© 27th Russian Particle Accelerator Conference, RuPAC 2021. All rights reserved.The study considers the development of the magnetic system of the 2.45 GHz ECRIS for the production of protons and double-charged helium ions. The magnetic field configuration is shown to be based on permanent magnets. The results of the simulation made by the Finite Element Method have been performed. To adjust the axial magnetic field profile the configuration with the alternating position of the ring magnets was analyzed. The double series construction of the bar magnets provides the adjustment of the radial magnetic field Brad at the chamber wall. Additional solenoids were introduced to the system for a corrective tuning of theBinj and Bext parameters and the axial profile minimum Bmin of the magnetic field distribution. Thus, the magnetic system is appeared to provide the mode switching between the ECR and the microwave operating modes.
