Method for growing superconductive film

摘要

A method for growing a superconductive film, comprising: (a) helically winding a tape substrate around the outer periphery of a cylindrical or columnar holder and (b) growing a superconductive film on the surface of the tape substrate by plasma flash evaporation, while rotating the holder and a cylindrical or columnar holder for a tape substrate for growing a superconductive film. According to the present invention, the heat contact between the holder and the tape substrate is stabilized and a high performance tape conductor can be obtained. In addition, degradation of superconductive performance possibly experienced, when the tape is used for a transmission cable or the like, can be lessened. Furthermore, the large area growth, which is the characteristic feature of plasma flash evaporation, is effectively utilized and production efficiency of a long tape conductor can be enhanced.
