The 25th Hiroshima International Symposium on Synchrotron
Radiation
Masahiro Katoh
Hiroshima Synchrotron Radiation Center, Hiroshima University
Hiroshima Synchrotron Radiation Center held the 25th Hiroshima International Symposium on
Synchrotron Radiation entitled "Materials Science using VUV-SX Synchrotron Radiation", aiming topromote the international and interdisciplinary exchange of information about materials scienceutilizing synchrotron radiation. In the last year, the 24th symposium was canceled due to the COVID19 pandemic. In this year, the situation was still difficult. Therefore, the organizing committee decided
to give up a face-to-face meeting and hold the symposium totally online, to ensure the safety ofparticipants.
The symposium started with the greeting from Prof. Shinichi TATE, Vice President of Hiroshima
University. Then, Prof. Kenya Shimada presented the present status of the facility and the recent
scientific results. Because the speakers in the scientific sessions were spreading out worldwide, thetimetable of the scientific session was unusual. It started with the flash oral presentations by the poster
presenters. Then, the online poster session started, in which 27 presentations (including 20 student
presentations) were made, focusing on the results of joint usage and research in the fiscal year 2019.
The poster presentations of the students were evaluated by all participants (other than students)
including invited speakers from Japan and overseas, and three student poster awards were decided asshown later.
At this symposium, the following topics were mainly discussed;-

High-resolution photoemission spectroscopy
Spin resolved photoemission spectroscopy
VUV-CD spectroscopy of biomolecules
Soft x-ray magnetic circular dichroism of nanomaterials
Light source accelerators and insertion devices.

In connection with these major topics, the following researchers were invited and gave talks on theircutting-edge research works;-

Songtian LI (National Institute for Quantum and Radiological Science and Technology, Japan),"A novel Graphene/Heusler Alloy Heterostructure for Advanced Spintronics"
K. ASOKAN (Inter University Accelerator Centre, India), "Role of Ion Beams in SrTiO3 andtheir Characterizations by Synchrotron Based Techniques"
Michiya FUJIKI (Nara Institute of Science and Technology, Japan), "Marvel CPL, CPLE, andECD Spectroscopy to Study the Origin of CD- and CPL-sign Inversion of D-/L-Camphor and
Colloidal pi-Conjugated Polymers"
Mohamed I. A. IBRAHIM (National Institute of Oceanography and Fisheries, Egypt),"Biomolecules Derived-Marine Ecosystems as Attractive Targets for SRCD Applications "Jaime SÁNCHEZ-BARRIGA (Helmholtz-Zentrum Berlin für Materialien und Energie GmbH,Germany), "Equilibrium and ultrafast response of topological matter to optical excitation"
Kenta KURODA (ISSP, University of Tokyo, Japan), "Electronic correlations of CeSb throughthe devil's staircase transition"
Shin-ichiro IDETA (UVSOR, Institute for Molecular Science, Japan), "Doping Dependence of
The Electronic Structure in Triple-layer Cuprate Bi2223"
Tatsuo KANEYASU (Saga Light Source, Japan), "Coherent Control of Atoms in the Extreme
Ultraviolet and Attosecond Regime by Synchrotron Radiation"－ 133 －

-

Yudai IZUMI (National Institute for Quantum and Radiological Science and Technology,
Japan), "An Application of Vacuum Ultraviolet Circular Dichroism Spectroscopy to Radiation
Biology: Secondary Structural Analyses of Histone Proteins".

These talks were divided into two time zones, evening of the first day and morning in the second day,considering the time zone of the oversea participants. After finishing all the scientific sessions, theclosing session was held, in which Prof. Okuda announced the winners of the best student poster
awards. The following students won the awards;-

Yudai Miyai (Hiroshima University), “High-resolution ARPES of heavily overdoped Bi2201 :evaluation of coupling parameters”
Shusuke Ozawa (Hiroshima University), “Low-energy electron-boson coupling in Sr2RuO4”
Toshiki Sakamoto (Yokohama National University), “Optical Activity Measurement of Amino
Acid Films by Circular Dichroism Spectroscopy”

This international symposium was successfully held in collaboration with the Japanese Society for
Synchrotron Radiation, with a total of 71 participants. We wish we could have the next symposium
face to face in the campus, welcoming the invited speakers overseas.
