Superconducting magnet devices are roughly divided into two types depending on their cooling method: immersion cooling type and forced cooling type. The configuration of the superconducting magnet device with both cooling methods is as follows.
It mainly consists of a superconducting coil and a coil container to house it and support the electromagnetic force it generates. The forced cooling type has advantages that the immersion cooling type does not have, such as being able to take a high current density and having a mechanically strong structure. It was necessary to cool it down. The heavy structure of the coil container due to the recent increase in the size of superconducting magnet devices,
This results in a significant increase in the time required to cool the superconducting coil. For this reason, methods have been considered to cool the coil container by providing a separate cooling system, such as installing a coiled pipe on the surface of the coil container, but the cooling area is limited.
The time required for cooling becomes enormous. Furthermore, when the cooling system is composed of coiled pipes or the like, there are drawbacks such as the flow rate of the refrigerant being restricted due to pressure loss in the pipes.

The superconducting magnet device 8 of the present invention is housed in a vacuum container 9 whose inner surface is provided with a radiation shield (not shown). The vacuum container 9 serves as a type of cryostat, and the superconducting magnet device 8 is connected to a vacuum pump 12 and a gas cylinder 13 via a port 7, an insulated pipe 10, and valves 11a, 11b, and 11c. Superconducting coil 1 is cooled from current lead 6 via valve 11e. At this time, the refrigerant that cools the superconducting coil 1 is bypassed via the valve 11g, and is passed from the outside of the superconducting coil 1 through the space between the superconducting coil 1 and the coil container 5, which is made up of the plugs 2, 3, and 4. Cool the coil and coil container,
It is led to a recovery system via a valve 11d. Here, the claws 2, 3, and 4 are constructed to have sufficient strength against the electromagnetic force generated by the coil, and to propagate the force to the coil container. As a result, when the temperature of the coil 1 and the coil container 5 is high, the pressure loss in the refrigerant flow path in the coil is large, so more refrigerant is supplied to the cooling system bypassed via the valve 11g. On the other hand, if the temperatures of the coil 1 and coil container 5 are low, the main cooling of the coil body is performed by closing the valve 11g and increasing the flow rate of refrigerant in the coil. When the coil 1 and coil container 5 are sufficiently cooled, the valve 11
d and 11g are closed, and the coil container 5 and the coil 1 are removed by the vacuum pump 12 via the valves 11a and 11c.
evacuate the space and insulate it.

The time required for cooling the coil is significantly shortened, and heat intrusion into the coil from the outside can be suppressed as much as possible. On the other hand, the valve 11c and the gas cylinder 13
By providing this, it is also possible to perform cooling using convection by filling the space between the coil 1 and the coil container 5 with gas and flowing a refrigerant into the coil.
This can also be used when heating the coil, and the heating time can be significantly shortened.
