Abstract: Disclosed is an disclosure pertaining to a cooling apparatus for a superconductor cooling container. The disclosed cooling apparatus for a superconductor cooling container comprises: an inner container which is disposed in an outer container and in which a superconductor is immersed in a liquid refrigerant; a refrigerator disposed outside the outer container to generate cold air; and a cryogenic maintenance device which is connected to the refrigerator and maintains the inside of the inner container in a cryogenic state.

Abstract: Disclosed is a bobbin structure for winding a superconducting wired rod, which can secure a minimum radius of curvature that can prevent a deterioration in mechanical properties and a decrease in the uniformity of electromagnetic force distribution, due to contraction and expansion acting on the wire rod during quenching of the superconducting wire rod, and which also can ensure uniformity of temperature over all portions of the superconducting wire rod by securing a cooling channel required for cooling of the superconducting wire rod.
