Abstract

We jointed BSCCO multi-filament tapes and evaluated their electrical properties. In the process, two superconductive-joint methods were used; the two multi-filament tapes were directly connected each other(MM joint), and were connected through the single-filament tape inserted between them(MSM joint). It was observed that critical current ratio and n value were 25-29% and 2.5-2.8 for MM jointed tape, and 34-53% and 3.7-4.2 for MSM Jointed tape, respectively. The higher electrical properties for MSM tape is considered to be due to that the presence of single core results in better interconnections of multi-filaments from the two tapes.
