Research Areas

"Deputy Director"
Intensity Upgrade:Hiroki OKUNO
Stable and Efficient Operation:Nobuhisa FUKUNISHI

The accelerator group pursues various upgrade programs of the next-generation heavy-ion accelerator facility, RI-Beam Factory (RIBF), to improve the accelerator performance and operation efficiency. We are also actively promoting the applications of the accelerator facility to a variety of research fields.

Research Subject

  1. Upgrade of beam intensity in RIBF accelerators
  2. Stable and efficient operation of RIBFaccelerators
  3. Effective maintenace of RIBF accelerators
  4. R&D of advanced accelerators
