Research Areas

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.

Research Subject

  1. The long term high stability of the RILAC operation.
  2. Improvement of high efficiency of the RILAC operation.
