The Nishina Center for Accelerator-Based Science consists of the following three divisions: Theoretical Research Division, Sub-Nuclear System Research Division, and Radioactive Isotope 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.
