Dr. Keiichi Tanabe

President of Superconducting Sensing Technology Research Association (SUSTERA)


Keiichi Tanabe received his M.E. in applied physics from The University of Tokyo in 1979 and then joined Electrical Communication Laboratories of Nippon Telegraph and Telephone Corporation (NTT). In 1980 he started to study thin films and Josephson junctions of Nb-based compound superconductors and received a Ph.D from The University of Tokyo in 1988. Since 1987 he had worked on HTS thin films, Josephson junctions, and their application to electronic devices as a visiting scientist at Cornell University (1987-1988) and a senior research engineer at NTT laboratories (1988-1995). In 1995 he joined Superconductivity Research Laboratory (SRL) of International Superconductivity Technology Center (ISTEC) as a division director. His R&D activities at SRL-ISTEC as a division director and finally the director general covered a wide range, not only electronic application of HTS thin films and junctions in SFQ devices and SQUIDs but also materials research such as search for new HTS materials, study on iron based superconducting thin films, and characterization of coated conductors. Since 2009 his major interest has been application of HTS SQUIDs with ramp-edge Josephson junctions to systems for field use such as TEM systems for exploration/monitoring of natural resources and NDE systems. Upon dissolution of ISTEC in 2016, he moved to SUSTERA which stemmed from the electronic devices division of SRL and has continued to direct the development of various systems using HTS SQUIDs. He has published over 350 journal papers on superconductivity. He has served the superconductivity society as the chairman of superconductivity division in Japan Society of Applied Physics (JSAP) (2003-2005), chairman of superconductive electronics committee in The Institute of Electronics, Information, and Communication Engineers (IEICE) (2007-2009), and ASC board member in electronics (2006-2012). He was also awarded a fellow of JSAP for the R&D of HTS Josephson junctions and their application.
