The low-temperature damper 10 surrounds the outer periphery of the coil mounting shaft 2 and has the function of reducing the amount of heat radiated from the outside to the cryogenic part. Further, a room temperature damper 5 constituting a vacuum container is arranged around the outer periphery of the low temperature damper 10 and is coupled to an end shaft 7. Further, a radiation shield plate 6 is coupled to the side surface of the heat exchanger 3 on the side of the end shaft 7 in order to reduce the amount of heat radiated from the end shaft 7 . This radiation shield plate has a disc structure, and a vacuum connection hole 13 connecting the space 9 and the space 8 is provided in the center.
The vacuum connection hole 13 constitutes a vacuum insulation layer within the rotor.
