Claim 7:
8. The superconducting magnet assembly of claim 1, wherein
the refrigeration component includes a switch component,
the switch component includes a thermal switch, the thermal switch including a activation mode configured to facilitate heat transfer between the first stage cold head and the radiation shield, and a deactivation mode configured to break or impede the heat transfer between the first stage cold head and the radiation shield;
the thermal switch includes a container, a cold end, and a hot end, a first end of the container being thermally coupled with the stage cold head through the cold end, and a second end of the container being thermally coupled with the radiation shield through the hot end; and
the container is a hollow structure filled with a transfer medium that transitions between a gas phase and a liquid phase based on a refrigeration temperature of the first stage cold head.
