摘要： A method is provided for cooling a high temperature superconductor such as an oxide superconductor to a lower temperature at a lower cost with a more simple system. A superconducting coil is attached to a cooling stage of a refrigerator. By immersing the superconducting coil on the cooling stage in liquid nitrogen, the superconducting coil is cooled rapidly. Then, the superconducting coil is further cooled by the refrigerator. By the cooling operation of the refrigerator, the liquid nitrogen is solidified. Thus, the superconducting coil is surrounded with solidifed nitrogen. The superconducting coil covered with the solidified nitrogen is further cooled by the refrigerator. In the superconducting coil cooled to a lower temperature and covered with solid nitrogen, quenching is suppressed to allow a higher current to be conducted.

摘要： An oxide superconducting coil is formed by winding a superconducting multifilamentary wire consisting essentially of a plurality of filaments consisting essentially of an oxide superconductor and a stabilizing material, consisting of silver or a silver alloy, covering the filaments. Superconducting phases of the filaments are substantially rendered monophasic, and c-axes thereof are strongly oriented along the thickness of the wire. Crystal grains of the superconductor forming the filaments are in the form of flakes extending longitudinally along the wire, while the same are bonded to each other. In a section of the wire, a ratio obtained by dividing a sectional area occupied by the silver or the silver alloy by that occupied by the filaments is not more than 3. In a magnetic field of at least 10 T, the coil exhibits a critical current value which is at least 60% of that exhibited by the wire itself forming the coil.
