Teaching content

I guide researches on improvement of cryogenic stability or enhancement
of magnetic field of large superconducting magnets. Otherwise, I guide
design studies on magnets for fusion reactors. Specific research subjects are (1) application of react-and-wind method to a A15 superconducting conductor, (2) mechanical characteristics and cryogenic stability of large superconducting conductors, (3) an analysis of cryogenic stability of the LHD helical coil, (4) a conceptual design of a superconducting magnet for fusion reactors, and so on.
