RIKEN Nishina Center for Accelerator-Based Science RILAC Team

Team Leader: Osamu Kamigaito (D.Sci.)

Research Summary

Osamu Kamigaito

Our team is responsible for the operation, maintenance, and upgrade of the RIKEN heavy-ion linear accelerator (RILAC), a unique variable-frequency linac that has been in operation since 1980. RILAC was upgraded in the 1990s as part of the RI Beam Factory (RIBF) project, and made a significant contribution to the synthesis and discovery of the element 113, nihonium. In 2019, a superconducting linac booster, SRILAC, was installed, and it will play a major role in the synthesis of heavier new elements, development of the technologies for production of medical radioisotopes, and as a powerful injector to RIBF.
