RIKEN Nishina Center for Accelerator-Based Science Ion Source Team
Team Leader: Osamu Kamigaito (D.Sc.)
Research Summary

Ion sources are critical devices that determine the performance of accelerator facilities. The Ion Source Team has produced several world-class ECR ion sources over a long period of research and development. We currently operate three ECR ion sources, including two superconducting ECR ion sources, to produce intense heavy-ion beams that are accelerated in the RI Beam Factory. We are also conducting research and development to further increase the intensity and stability of the beams.
