Research Areas

Our aim is to operate and develop the ECR ion sources for the accelerator-complex system of the RI Beam Factory. We focus on further upgrading the performance of the RI Beam Factory through the design and fabricatin of a superconducting ECR heavy-ion source for production of high-intensity uranium ions.

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
