Research Areas

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.

Research Subject

  1. Operation and development of the ECR ion sources
  2. Development of a superconducting ECR heavy-ion source for high-intensity uranium ions
