1 is a permanent current switch which is housed in an image chamber 15 formed at a substantially central portion of the superconducting coil 11 to set a coil current flowing through the superconducting coil 11 to a permanent current mode. The refrigerant reservoir 17 is a storage tank disposed above the outer tank 7 and containing liquid helium 18 as a refrigerant.
The liquid helium is supplied to the inside of the chamber 0 and the compartment 15 and the like.

[0007]

The conventional superconducting magnet device is constructed as described above, and since the permanent current switch 14 is disposed substantially at the center of the superconducting coil 11, an image chamber 15 for accommodating the permanent current switch 14 is formed.

There was a problem. In addition, the connection between the permanent current switch 14 and the superconducting coil 11 and the external current lead must be made in a narrow space in the duct for guiding the liquid helium 18 into the compartment 15, so that the operation is very difficult. There was a problem. When the image chamber 15 vibrates, the bobbin around which the superconducting wire of the switch element 14a constituting the permanent current switch 14 is wound is deformed by vibration,
There has been a problem that the stability of the permanent current switch is reduced due to a small amount of frictional heat generated between the superconducting wire and the bobbin.
