In 1931, Dr. Yoshio Nishina’s laboratory was established in RIKEN. For more than 80 years since then, RIKEN has continued to promote accelerator-based science in Japan and maintained its position as the world’s front runner in the field. On the New Year’s Eve of 2015, a significant milestone was achieved when the naming rights for element 113 was granted to a RIKEN research group. In November 2016, the International Union of Pure and Applied Chemistry (IUPAC) officially approved the name and symbol for the new element, “nihonium” and “Nh” proposed by the research group led by Dr. Kosuke Morita. Nihonium thus earned a permanent seat at the periodic table. It was an outstanding achievement, to be the first group not only in Japna but in Asia to have discovered a new element and earning naming rights to it.

The RI-beam factory (RIBF), whith the linear accelerator “RILAC” at its first stage that synthesized the new element, is the symbol of the RIKEN Nishina Center. Housing the world’s largest superconducting ring cyclotron and superconducting RI-beam separator, BigRIPS, RIBF’s capacity to produce RI-beams is unparalleled in the world.

The primary mission of Nishina Center is to unravel the mystery of the genesis of the elements by investigating the nature of nuclei and their constituents, elementary particles. The center also aims to explore the potential industrial application of its research on nuclei and elementary particles to agriculture, medicine and other such fields. Incorporating RIKEN’s strength as a multidisciplinary research institute for natural science, Nishina Center promotes a wide range of cutting-edge research and development, a path pioneered by Dr. Nishina in his days. Nishina Center was named after him to honor the spirit of this great scientist.

The Nishina Center for Accelerator-Based Science consists of the following three divisions: Theoretical Research Division, Sub-Nuclear System Research Division, and Radioactive Ion Beam Factory (RIBF) Research Division.
The Theoretical Research Division explores the fundamental laws of physics and performs theoretical research on elementary particles and nuclei.
The Sub-Nuclear System Research Division conducts experimental research on elementary particles, nuclei, and materials physics using particle beams of protons, neutrons, and muons at the BNL Research Center (United States) and at the RIKEN Facility Office at the RAL (United Kingdom).
The RIBF Research Division performs research and development for various fields. In particular, it provides user support related to heavy ion accelerators at RIBF.

The completion of RIBF heralds a new era in the field of nuclear physics. By producing a large number of unstable nuclei, studying their properties and finding the ultimate picture of nuclei, we will be able to uncover the process by which the heavy elements were formed in the universe. The powerful heavy ion beams will not only be used for nuclear physics research but also for various applications purposes. Since the new capabilities of RIBF will broaden the research potential immensely, Nishina Center will commit itself to upgrading research environment and operation system of RIBF for the worldwide users to achieve outstanding results. Your continued cooperation and support would be greatly appreciated.
