Super-High Magnetic Field NMR Utilization Unit

Unit Leader: Yoshinori Yanagisawa (Ph.D.)
Yoshinori  Yanagisawa(Ph.D.)

The goal of the unit is to develop a 1.2-1.3 GHz (28-30 Tesla) class super-high magnetic field nuclear magnetic resonance (NMR) system to make breakthroughs in the fields of life sicence 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 acuarate magnetic field, super-high magnetic field generation and coil proptection.

Research Subjects

  • Development of super-high NMR
  • High-temperature superconducting magnet technology
