    Magnetic System with Adjustable Characteristics for Electron Cyclotron Resonance Ion Source with Operating Frequency of 2.45 GHz
    (2021) Artamonov, K. G.; Dmitriyev, M. S.; Zhigailova, M. I.; Дмитриев, Максим Сергеевич; Жигайлова, Марина Ивановна
    © 2021, Pleiades Publishing, Ltd.Abstract: This paper presents a description of the magnetic system of the developed electron cyclotron resonance (ECR) ion source with an operating frequency of 2.45 GHz for producing protons and doubly charged helium ions. The results of numerical simulations of the magnetic system of the ECR source built on permanent magnets are presented. A configuration with the possibility of moving the ring magnets of the injection and extraction area to adjust the magnetic field distribution, in particular, the maximum values of Binj and Bext at the plasma chamber axis, and with the possibility of moving the bars of the sextupole magnet in the radial direction to adjust the magnetic field Brad at the chamber boundary is presented. To obtain the magnetic field profile corresponding to the mode of the microwave source, the design of the magnetic system with the use of additional solenoids providing adjustment of Binj and Bext values within the required limits as well as adjustment of the minimum magnetic field Bmin on the chamber axis at fixed position of all ring magnets is considered.

    MAGNETIC SYSTEM WITH VARIABLE CHARACTERISTICS FOR A 2.45 GHz ECRIS
    (2021) Dmitriev, M. S.; Zhigaylova, M. I.; Artamonov, K. G.; Ivanov, O. A.; Дмитриев, Максим Сергеевич; Жигайлова, Марина Ивановна; Иванов, Олег Александрович
    © 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.
