CURRENT LEAD FOR SUPERCONDUCTING MAGNET AND MANUFACTURE OF THE SAME

摘要

PROBLEM TO BE SOLVED: To reduce the quantity of heat entering at the non-conduction time, eliminate sliding and fluctuation between component members due to oscillation at travelling of a superconducting magnet and thus restrain heating due to sliding friction in a current lead for superconducting magnet. SOLUTION: A current lead for a superconducting magnet 12A has a structure, in which a plurality of conductors for electrical conduction 13a and electrical insulators 14a and 14b are integrated and filled in an outer cylinder 15 with a cooling gas flow path 16a left at a part therein. By spirally forming the cooling gas flow path 16a along the direction of flow of a current, convection of a cooling gas can be prevented, and the cooling effect of the conductors for electric conduction 13a can be enhanced.
