Unit Leader
Yoshinori Yanagisawa  Ph.D.

C116, Central building, 1-7-22 Suehiro-cho, Tsurumi-ku, Yokohama, Kanagawa 230-0045


Research Area

The goal of the unit is to develop a 1.2-1.3 GHz (28-31 Tesla) class super-high magnetic field nuclear magnetic resonance (NMR) system to make breakthroughs in the fields of life science and material science. "High-temperature superconductor (HTS)" technology is the keyword for achieving such a high magnetic field. We make basic experiments and numerical simulations on HTS coils and develop HTS NMR systems with technologies for highly accurate magnetic field, super-high magnetic field generation and coil protection.
