Abstract

Many laboratories have been involved in the development of electron cyclotron resonance (ECR) ion source for linear accelerators all over the world. The superconducting magnets for the 28-GHz ECR ion source consist of a Hexapole Coil and four Solenoid Coils. The Solenoid Coils produce an axial mirror magnetic field, and the Hexapole Coil produces a radial magnetic field. In this paper, the specifications of the superconducting magnets for the 28-GHz ECR ion source are deduced by using the finite-element method (FEM) to perform simulations. The research presents the result of analyses on the magnetic field and the electromagnetic force of the superconducting magnets for the ECR ion source for different the conditions of the Inner Yokes. The design of the Inner Yokes for a Hexapole Coil is performed to enhance the characteristics of the radial magnetic field and to lower the operating current level.
