Abstract :
This paper presents the magnetic shielding characteristics of a complex structure with multiple high-Tc superconductors (HTS) coaxially superposed and ferrite powder padding, and its effect on the critical current increase of a HTS current lead. A model HTS current lead is inserted into the complex structure and cooled by LN2. The magnetic flux density in the innermost HTS pipe with and without the ferrite powder, and the critical current of the current lead were measured and the various complex structures were evaluated.<>
