Superconducting experts from Tohoku University and Kyushu University visited IEECAS

Prof. Satoshi Awaji from the High Field Laboratory for Superconducting Materials, Institute for Materials Research (IMR), Tohoku University in Sendai, Japan and Prof. Takanobu Kiss from the Dept. of Electrical Engineering, Kyushu University in Fukuoka, Japan visited IEECAS and gave lectures to the researchers and students on Nov. 26th, 2015. Prof. Yanwei Ma, the director of the New Superconducting & Energy Materials Group, IEECAS presided over the lectures.

In the lecture entitled with “Flux pinning property in RE123 and Sr122 superconducting tapes”, Prof. S. Awaji introduced the flux pinning types and property in RE123 and Sr122 superconducting tapes, respectively. He said similar flux pinning behaviors were reported in both RE123 and Sr122 superconducting tapes. People can learn from the flux pinning study in RE123 tapes, in order to introduce the pinning centers in the iron-based superconducting wire and tapes. Prof. T. Kiss gave a report entitled with “Development of novel characterization techniques for forefront superconducting materials”. First, he summarized their recent research activities on the development novel characterization techniques including reel-to-reel scanning Hall probe microscopy and multi-scale hybrid microscopy to clarify current blocking obstacles in HTS superconducting tapes, MgB2 round wires and Fe-based superconductors. Then, hardware-in-the-loop-simulation (HILS) to test a proto-type superconducting cable for an electric train system under the environment of grid network was also introduced by him. After the lectures, the audience discussed some questions with the visitors.

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.

Prof. T. Kiss is expert in the area of superconducting material characterization. He has developed novel measurement techniques to clarify local electromagnetic properties of superconducting materials. These studies focus on the understanding and resolving key performance issues of superconducting forefront materials.
