摘要：

The 28-GHz ECR (electron cyclotron resonance) ion source is under development to supply various beams from protons to uranium at the RISP (Rare Isotope Science Project). The superconducting magnet system for a 28-GHz ECR ion source consists of four solenoid coils and a saddle-type sextupole. A numerical simulation was accomplished to meet the design requirement of the ECR ion source by using the KOBRA3-INP code, which is the three dimensional ion optics code, to optimize the extraction system. The influence of the three-dimensional magnetic field and the space charge effect was considered to extract the highly-charged ion beam. In this paper, the design results for the extraction system were reported in detail.
