World record of a magnetic field strength for fully-superconducting magnets
The research team of RIKEN, National Institute for Materials Science, Japan Superconductor Technology, JEOL RESONANCE and Chiba University has developed a superconducting magnet generating a 27.6 Tesla magnetic field (20/Jan/2016), which is a world record of magnetic field strength for fully-superconducting magnets (as of 01/Apr/2016).
This success has been archived by a new combination of high-temperature superconducting (HTS) inner coils and low-temperature superconducting (LTS) outer coils (see Figure). The technical concept will enable to develop a compact super-high field NMR with an operating frequency of much higher than 1 GHz (23.5 Tesla), that is the goal of their development.
