CURRENT LEAD OF SUPERCONDUCTING APPARATUS

摘要

PURPOSE: To realize compactness of an outer shape of a superconducting apparatus by reducing an amount of heat entering from an outside by forming a current lead to a coil form. ;CONSTITUTION: A current lead is formed to a structure wherein coil-like conductors 5d, 5e having almost the same diameter are wound around an insulation bobbin 5c of high heat resistance for an arbitrary number of turns in the opposite right and directions, and both ends thereof are shortcircuited on the respective electrodes 5b. A superconductor is used for an electric line connecting a current lead 5 and a superconducting coil. In a current lead constituted in this way, the conductors 5d, 5e are made a parallel non-inductive coil. Thereby, in a current lead, a space occupied inside a superconducting apparatus is reduced, heat entering from an outside is reduced and compactness of an outer shape of a superconducting apparatus is realized.;COPYRIGHT: (C)1995,JPO
