Development of Second Generation High TC Superconducting Tapes

Owing to the high performance, the second generation (2 G) high T_C superconducting tapes based on yttrium barium copper oxide have attracted much attention of the researchers worldwide to develop the processing techniques for application. In recent years, a series of the achievements have made the 2 G tapes become the focus of the superconductor research. An overview of the recent progress of 2 G superconductor tapes was provided, and the structures and the fabrication techniques of coated conductor on Ni and Ni alloy were described systematically.
