Outline of Final Research Achievements

We developed the cryogenic thermography for magnet application of the high temperature superconducting tapes to solve the local heating (hotspot) problem.
On the first year, Eu-TFC is revealed to be applicable for cryogenic thermography by using fluorescent spectroscopy at low temperature and high field. In parallel, a cryostat with an imaging system for the cryogenic thermography with a high field and a large current capacity was developed.
On the second (last) year, hotspots in REBCO tapes and a REBCO coil were observed using the cryostat. The normal zone propagation was visualized in the REBCO tapes. Finally, the hotspot the degradation area in the REBCO coil was identified at the overcorrect state by using the cryogenic thermography.
