Abstract
The present invention is to provide a structure that can effectively reduce quench in an open superconducting magnet. In order to do so, a pair of superconducting magnets is respectively provided with a primary coil, a shield coil to suppress a leakage magnetic field of the primary coil, and a coil bobbin. The coil bobbin has a cylindrical part on which the primary coil is wound, a ring-shaped end plate on which the inner periphery part is fixed to an end of the imaging space side of the cylindrical part, and a support member preventing the outer periphery part of the ring-shaped end plate from being displaced on the imaging space side. Hence, deformation of the end plate is suppressed to prevent deformation of the primary coil. This can reduce quench caused by the deformation of the primary coil.
