Superconducting Magnets of Ion Sources

Today, accelerator installations of various configurations are widely used in the fields of medical and scientific activities. One of the main directions of work on the development of accelerator technology is to increase the energy of beams of charged particles, which is achieved by improving the magnetic system of the accelerator and the injection system. This article is devoted to the development by specialists of Efremov Research Institute of Electrophysical Equipment of superconducting magnets used in injection systems (ion sources) of various types. The article presents two superconducting magnets of different configurations, used: in a high-current injector of multiply charged ions based on an ECR (electron cyclotron resonance) type superconducting ion source with a magnetic field induction on the axis on the injection side of 4 T, on the extraction side of the ion beam 2–2, 5 T, and in the electron beam source of multiply charged ions of the external injection system of the cyclotron complex with a magnetic field induction of 5 T, respectively. The article provides justification for the choice of the main parameters of the magnetic system and its protection, electromagnetic, thermal and mechanical analysis of the selected configuration of the magnetic system.
