Quench Characteristics of a kA class Superconductor

kA 급 초전도도체의 ？치 특성

As the earlier step of the fabrication of the SMES magnet, a kA class superconductor with a high copper ratio was selected as a candidate conductor. The superconductor was tested in two points of view, which are basic and important in development of the SMES magnet. First stabilities of the superconductor against localized disturbances such as wire motions were measured by using a wire heater. Second the quench current characteristics for different charage rates were also tested.
