Description:

High-Tc superconducting magnetic flux transformers with pickup coils of diameter 100 mm were prepared using an RE123 commercial superconductive tape. A superconducting flux transformer requires closed circuit containing a superconductive joint which is difficult to prepare for cuprate high-Tc superconductor. Using the cut-and-wind method, seamless and large bore coils were equipped to the flux transformer, which is advantageous for non-destructive estimation and geological magnetic survey. The magnetic flux transfer of the applied static field caused by the spontaneously induced superconductive shield current at liquid nitrogen temperature was confirmed, and the static field transfer efficiency depending on the inductance of the coils in the flux transformer was estimated.
