1 Part 1 Overview of current status (Prof. Naoyuki Amemiya)

Naoyuki Amemiya
Professor, Department of Electrical Engineering, Kyoto University
Speaker Biography:

Professor Naoyuki Amemiya received his Dr. Eng. Degree from the
University of Tokyo in 1990. He joined Yokohama National University in
the same year (Lecturer in 1992; Associate Professor in 1993;
Professor in 2005) and transferred to Kyoto University in 2008. He
stayed at the National High Magnetic Field Laboratory in 1996 as a
Visiting Scientist and at University of Twente from 2000 to 2001 as an
Exchange Scientist between JSPS and NWO.

His research interests include electromagnetic phenomena of
superconductors, magnet applications of superconductors, and
large-current high Tc superconductors. He has been involved in various
R&D projects funded by the Japan Science and Technology Agency, the
New Energy and Industrial Technology Development Organization, etc.

He has been serving for various international conferences. He is the
Senior member of IEEE and the members of various academic societies in
Japan.

Speaker: Naoyuki Amemiya (Kyoto University)

2 Part 2: Measurements of ac loss in SCSC cables exposed to ac magnetic field (Mr. Mao Shigamasa)

Mao Shigemasa
Graduate student, Department of Electrical Engineering, Kyoto University
Speaker Biography:

Mao Shigemasa received the B. Eng. degree in electrical engineering from Kyoto University, Kyoto, Japan, in 2021. He is currently working toward the Dr. Eng. degree in electrical engineering in Kyoto University. He is to be the Research Fellow of Japan Society for the Promotion of Science, DC1, from 2023 to 2026.

His research interests include measurements and reduction of ac losses in high temperature superconductor cables. He has presented at international conferences on applied superconductivity such as Applied Superconductivity 2022 (ASC 2022).

3 Part 3: Electromagnetic phenomena in SCSC cables carrying dc/ac current under ac magnetic field (Prof. Yusuke Sogabe)

Yusuke Sogabe
Assistant Professor, Department of Electrical Engineering, Kyoto University
Speaker Biography:

Dr. Yusuke Sogabe received his Dr. Eng. Degree from Kyoto University in 2019.
The title of his Ph.D. thesis is "Research on ac losses and shielding-current-induced fields aiming to application of HTS magnets to particle accelerators."
In the same year, he joined Kyoto University as an assistant professor in Prof. Amemiya's group.

His research topics are application of high Tc superconductors to magnets,
evaluation of electromagnetic properties of high Tc superconducting coils and cables,
and numerical analyses of high-Tc superconducting coils and cables.

He was a Research Fellow of Japan Society for the Promotion of Science, DC1, when he was a doctoral student in Kyoto University.
He has received several awards equivalent to best presentation awards at international conferences on applied superconductivity such as International Conference on Magnet Technology.
