01　Sr Ring

The SR Ring (Synchrotron Radiation Ring), the core light source of our institute, is a facility that generates "synchrotron radiation"—an intense beam of light produced when high-speed electrons are accelerated and guided along a circular orbit by magnetic fields. This radiation is exceptionally bright and covers a wide range of wavelengths, making it an essential tool for various fields, including material structure analysis, the development of new materials, and life science research. The SR Ring serves as a fundamental apparatus that underpins modern scientific research.

02　Beamlines

The defining characteristic of HiSOR’s beamlines is their specialization in the low-energy region, ranging from vacuum ultraviolet (VUV) to soft X-rays (several eV to several hundred eV). This energy range is ideal for the direct observation of electronic states that determine the properties of materials. Our facility features more than ten highly unique experimental stations, including high-resolution Angle-Resolved Photoemission Spectroscopy (ARPES) and world-class, high-efficiency spin-polarized spectroscopy systems. Furthermore, we offer Vacuum Ultraviolet Circular Dichroism (VUV-CD) spectroscopy, which is highly effective for the structural analysis of chiral molecules. As a joint-usage hub for both domestic and international researchers, HiSOR supports cutting-edge research across a wide spectrum of fields, from material science to life sciences.

03　OFFLINE INSTRUMENT

HiSOR’s offline experimental systems enable independent measurements without the use of synchrotron radiation, as well as advanced sample preparation and characterization to complement synchrotron experiments. Key facilities include the Scanning Tunneling Microscope (STM), which allows for the direct observation of atomic arrangements under cryogenic and ultra-high vacuum conditions, and the Laser-based Angle-Resolved Photoemission Spectroscopy (Laser-ARPES) system. By utilizing a deep-ultraviolet laser as a light source, our Laser-ARPES achieves world-class energy resolution.
