PURPOSE:To enhance the uniformity of a uniform magnetic field space by provid ing a portion in which a winding pitch is rough in case of winding a superconducting conductor in a solenoid. CONSTITUTION:Superconducting conductors 9 are divided to five types such as first, second, third, fourth and fifth coils 3, 4, 5, 6 and 7, and sequentially wound in a solenoid state from the bore side near a cylindrical bobbin 1. An interlayer space 10 made, for example, of glass cloth is laid between the layers. When the winding pitch of the conductors 9 is increased larger than one conductor and roughly wound, the conductors are wound while holding a spacer 11 between windings between conductors 9 and 9. The spacer 11 employs an insulated metal wire. The conductors 9 can use one continuous conductor for each coil without altering its sectional shape to prevent an electric resistance from generating or an irregular magnetic field from generating due to the connection of the conductor 9 on the way. |
