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
