PURPOSE:To enhance the cooling efficiency of a superconductive coil by providing a plurality of oblique grooves on a spacer formed between superconductive coils, forming a groove on the inner surface of a container containing the coil and connecting the groove to the striped grooves of the spacer, thereby forming a cooling channel. CONSTITUTION:An oblique groove 11a is formed on the surface parallel to the laminar direction of a superconductive wire 11 forming a superconductive coil, an interlayer spacer 12 is arranged in the laminar direction of the wire 11, and interturn spacer 13 is arranged in the turning direction. With this construction, the spacer 13 is formed with the same width as the width of the wire 11 in the turning direction in contact with the spacer 12, and an oblique groove 13a connected to the striped groove 11a of the wire 11 is provided on the surface parallel to the laminar direction of the spacer 13. A plurality of oblique grooves 15 respectively connected to the oblique striped grooves 11a, 13a and a groove 16 vertically connected to the groove 15 to the surface parallel to the laminar direction are provided on the surface parallel to the turning direction of the inner surface of a helium container 14 containing the grooves, and cooling channel 1 is formed of these striped grooves and the groove. |
