Advanced Superconducting Wire Group

• We are investigating the superconducting wires and related technologies (the stabilization, cabling, coil winding) used under the low-temperature and high magnetic fi eld for the high energy particle accelerator, fusion reactor, high resolution NMR and etc.
  
• In particular, we promote the development of wire processing technology for A15 typed metallic compound superconductors, such as Nb3Al and Nb3Sn.

• The PDCA cycle of new superconducting wire fabrication and high fi eld performance evaluation.
  
• Fine multi-fi lamentary wires fabricated through the micro composite of diff erent metals.
  
• Microstructural control through the metallurgical approach using the third-element addition, severe plastic deformation, and etc.
  
• Microstructural control through the thermodynamic approach using the quenching, massive phase transformation, diff usion reaction and etc.
  
• Critical current measurements using 18T superconducting magnet and 30T hybrid magnet.
