PURPOSE:To utilize a power lead wire as an absorber of a frictional heat occurring between a coil and a support fitment for a permanent current mode since the power lead wire used in energizing a superconducting coil is not used and thus the space is wasted when the superconducting coil is the permanent current mode. CONSTITUTION:A power lead wire 6 is connected to a start and an end of winding of a superconducting coil 1 and is wound in an alignment close winding by one layer of coil and is integrally molded in the coil 1. The molded body is tightened by a linear 7 and a support member 8 and is held in an inner bath 9 with a cryogenic temperature. Accordingly, a frictional heat occurring between the coil 1 and the support member 8 due to a vibration from the outside is absorbed by the power lead wire 6, and a quenching of the superconducting coil 1 is prevented. |
