The Critical Current Measurement of HTS tapes According to Bending Diameter

굽힘 반경에 따른 HTS tape 임계전류 측정

High temperature superconductor (HTS) tapes are now commercially available for practical applications to apply various purposes. However HTS tapes show different electrical and mechanical characteristics, according to the manufacturers who are trying to apply various fabrication processes and treatments. From the viewpoint of an application it is very important to investigate the properties of HTS tapes under mechanical stress because the tapes will be wound with twisting and tension in applications such as magnets and cables. Thus, we studied characteristics of HTS tapes and measure critical current under bending, considering of a mechanical conditions. A description of some typical results will be presented with discussions.
