摘要：

YBCO is currently one of the most widely used second-generation high temperature superconducting (HTS) materials. Compared with the first-generation HTS materials represented by BSCCO, the application of YBCO on the current lead can effectively reduce the 4K thermal load and achieve better stability. This paper introduces the research progress of YBCO soldered stacked conductor based on 65 mu m thickness YBCO film conductor with copper stabilizing layer. The electrical properties of the soldered stacked conductor, including the self-field dependence of the critical current, were tested and analyzed. In this paper, the thermal conductivity of the conductors at 4K is also tested by experimental platform based on GM cryocooler. The differences between superconducting stacked conductors in current lead applications and magnet applications were discussed.
