Claim 0:
1. A superconducting magnet assembly, comprising:
a cryostat, including
an outer vessel;
and
a radiation shield disposed within the outer vessel;

a superconducting magnet configured to generate a main magnetic field and disposed in the radiation shield; and
a refrigeration component at least a portion of which is disposed within the outer vessel, including
a refrigerator including a first stage cold head and a second stage cold head, the second stage cold head being configured to cool the superconducting magnet to a superconducting state, the first stage cold head being configured to cool the radiation shield; and
a transfer component, the transfer component being thermally coupled with the second stage cold head of the refrigerator and the superconducting magnet, and the transfer component including a transfer pipeline, wherein
the transfer pipeline is a hollow closed structure filled with a transfer medium that transitions between a gas phase and a liquid phase based on a refrigeration temperature of the refrigerator, a first end of the transfer pipeline being thermally coupled with the second stage cold head of the refrigerator, a second end of the transfer pipeline being thermally coupled with the superconducting magnet, and
the transfer pipeline includes a first transfer pipeline and a second transfer pipeline, a first end of the first transfer pipeline being connected with a first end of the second transfer pipeline so that the first transfer pipeline and the second transfer pipeline are in fluid communication, the first transfer pipeline being disposed in a vertical direction, the second transfer pipeline being at an angle with the first transfer pipeline, a second end of the first transfer pipeline being thermally coupled with the refrigerator, and a second end of the second transfer pipeline being thermally coupled with the superconducting magnet.
