Description
The purpose of this work is to search for the optimal design and arrangement of magnets to ensure the correct and uniform distribution of the magnetic field in the plasma chamber of the ECR source, using the DECRIS-5M source as an example.
In this paper we investigate the influence of external magnetic fields created by solenoids in the area of a hexapole magnet from the point of view of demagnetization, as well as the selection of materials to minimize this effect. Also, we consider the influence of the material choice on the service life of magnets.
Numerical simulations were carried out using the COMSOL Multiphysics software package. In addition, we have carried out magnetic field measurements of the DECRIS-5M source hexapole magnet. The results obtained can be used to improve the characteristics of existing ion sources and for development of the new sources.
