Prof. Kazuo Watanabe, Prof. Satoshi Awaji and Dr. Hidetoshi Oguro from the High Field Laboratory for Superconducting Materials, Institute for Materials Research (IMR), Tohoku University in Sendai, Japan visited our institute and gave lectures to the researchers and students on Sep. 29th, 2014. Prof. Yanwei Ma, the director of the New Superconducting & Energy Materials Group, IEECAS presided over the lectures.
In the lecture entitled with “New construction project of high static magnetic field facilities in Japan”, Prof. K. Watanabe presented a brief review on the global state of the art for high-field magnets and their applications in magneto science. He also introduced the plan of developing high magnetic field facilities in Japan in the future, including 25 T, 30 T cryogen-free superconducting magnets (CSM), a 35 T resistive magnet and a 47 T cryogen-free hybrid magnet (CHM). Prof. S. Awaji gave a report entitled with “Development of a 25 T cryogen-free superconducting magnet”. First, he introduced the recently developed 20 T CSM, which was upgraded from an 18 T CSM. Then he discussed some technical problems in the design for the superconducting coils of the 25 T CSM. In Dr. H. Oguro’s presentation “CuNb/Nb3Sn Rutherford cable development”, he introduced his work on enhancing the superconducting and mechanical properties of the CuNb/Nb3Sn Rutherford cables, which will be used as superconducting coils in 25 T CSM. After the lectures, the audience discussed some questions with the three visitors.
Prof. K. Watanabe, the director of the High Field Laboratory for Superconducting Materials, Institute for Materials Research (IMR), Tohoku University, is a famous expert in applied superconductivity. His research mainly focuses on high static field superconducting magnets. He has directed the development of the world’s first cryogen-free superconducting magnet and a hybrid magnet with high magnetic field up to 31 T.
Prof. S. Awaji has been working on the YBCO superconducting materials for many years, and also made great contributions to the development of high-field superconducting and hybrid magnets in IMR, Tohoku University.
Dr. H. Oguro is interested in the superconducting and mechanical properties of superconducting wires for high magnetic field generation. He has published more than 100 research papers in international journals.
