SUPER-CONDUCTING MAGNET DEVICE FOR GENERATING HORIZONTAL MAGNETIC FIELD USING CURVED ANNULAR OR ELLIPTICAL SHAPED COILS

摘要

This invention relates to a super-conducting magnet device for generating a horizontal magnetic field. To generate a horizontal magnetic field, one or more pairs of super-conducting coils are arranged on opposite sides of a cryostat. The horizontal magnetic field is generated inside of the magnetic field use Space (S). It is possible to improve the properties of the horizontal magnetic field in the magnetic field use Space (S) by employing curved annular or elliptical shaped super-conducting coils (E, E', E1, E2, E3, E1', E2', E3'). The curved annular or elliptical shaped super-conducting coils generate and distribute the magnetic forces more effectively than the saddle type super-conducting coils or solenoid type super-conducting coils. It also has the merit of being easy to manufacture, and shortens the manufacturing period compared to conventional super-conducting coils. It brings a 15% improvement of the magnetic field compared with solenoid type super-conducting coils using the same wire length for windings.
