Research Areas

In order to realize stable and efficient operations of RIBF accelerator complex, various improvements including beam diagnostics, computer control, power supplies have been performed. Our final goal is to establish simulation-based operation of RIBF accelerator complex.

Research Subject

  1. Improvement on the beam transmission along the multi-stage accelerator system.
  2. Development of beam diagnosis.
  3. Development of computer control.
  4. Bending-power upgrade of fRC.
  5. High-performance operation of RILAC2
