Recovery Current Characteristics of the SC conductor for a $\mu$ SMES

$\mu$ SMES용 초전도도체의 회복전류 특성

We are developing a small-sized superconducting magnetic energy storage ($\mu$ SMES) magnet with the storage capacity of a few megajoules, which provides electric power with high quality to sensitive electric loads. As the earlier step of the fabrication of the $\mu$ SMES magnet, this paper describes recovery current experimental results of a kA class superconductor. Recovery current of a superconductor was tested in two points of copper ratio and cooling effect.
