Research Topics, Overview of the research

Research Topics
Ac losses in superconductors, stability of superconductors, high Tc superconductor magnets, medical applications of superconductors, power applications of superconductors, various applications of electromagnetism, nuclear fusion
Overview of the research
From the viewpoints of applications, the major advantages of superconductors are current transport with extremely small energy dissipation and generation of high magnetic fields. Prof. Amemiya’s research interests in the area of fundamental technologies for superconductor applications include ac losses in superconductors, which is the loss generated when superconductors are exposed to temporally-changing magnetic fields, and the stability of superconducting state of superconductors carrying transport currents. He also studies on high Tc superconductor magnets for particle accelerators for cancer therapy and large-current high Tc superconductors, which is one of the key components of large-scale applications of superconductors.
