Title:
MANUFACTURE OF SUPERCONDUCTING COIL
Document Type and Number:
Japanese Patent JP3199782
Kind Code:
B2
Abstract:
PURPOSE: To suppress the occurrence of temperature rises in a superconducting coil by improving the heat conduction in the coil.
CONSTITUTION: In this manufacturing method of such a superconducting coil that the first insulation-to-the-earth layer 2, a coil 3 composed of a superconducting conductor, and the second insulation-to-the-earth layer 4 are closely arranged on the internal surface side of a cylindrical cooling body 1 that becomes an outer bobbin in a state where hey are integrally fixed to each other and an inner plate 5 is provided so as to cover the layer 4 side surface, the coil 3 is formed by winding the superconducting conductor around the inner plate 5 with the layer 4 in between after the plate 5 is put around a temporary bobbin 6. Then, after the cooling body 1 is put on the coil 3 with the layer 2 in between, the inner plate, coil, and the first and second insulation-to-the-earth layers are integrally fixed to each other by impregnating them with a resin. Then this superconducting coil is obtained by removing the temporary bobbin 6.
