CONNECTING METHOD FOR SUPERCONDUCTING COIL

PURPOSE:To prevent deterioration of cooling efficiency by conducting a coil-to- coil connection completely in forced-cooling type superconducting coils having the structure in which a superconducting lead wire is surrounded by sheathing material. CONSTITUTION:A terminal tube 3A, with a connecting flange 4A, is provided on one end of a first superconducting coil, one end of afotesaid terminal tube 3A is connected to the sheathing material 2A of the superconducting coil, the other end of the terminal tube 3A is connected to the superconducting wire 1A of the superconducting coil wire, and then the superconducting wire 1A of the first superconducting coil is connected to the superconducting wire 1B of the second superconducting coil. A terminal tube 3B, with a connection flange 4B, is provided in such a manner that the above-mentioned connected parts are enclosed, one end of the terminal tube 3B and the other end of the terminal tube 3A are connected, and the other end of the terminal tube 3B and the sheathing material 2B of the second superconducting coil are connected.
