    摘要: A cryogenic cooling apparatus is provided, wherein the degree of freedom of installation and use is increased without deteriorating the reliability or stability and the range of uses of the apparatus is also increased. A coil unit and a refrigeration unit are positioned such that a second heat conductive member disposed on an extendible wall of a vacuum container and a fourth heat conductive member disposed on an extendible wall of another vacuum container face each other coaxially. In this state, the coil unit and refrigeration unit are relatively moved to approach each other, and thus the second heat conductive member and fourth heat conductive member come in contact. If the coil unit and refrigeration unit are further moved, the extendible wall extends and consequently the second heat conductive member comes in contact with a first heat conductive member. In addition, the extendible wall contracts and consequently the fourth heat conductive member comes in contact with a third heat conductive member. Thus, a superconducting coil is thermally connected to the refrigeration unit so that the superconducting coil is cooled.

    摘要: In the adiabatic apparatus of the present invention, a vessel includes an adiabatic layer in which an object is taken. A plurality of thermal shield plates are located in the adiabatic layer. Each thermal shield plate concentrically surrounds the object. A temperature control section cools or heats the object and the plurality of thermal shield plates. A switch section thermally connects the temperature control section to the plurality of thermal shield plates and the object if temperature of the plurality of thermal shield plates and the object is controlled, and thermally separates the temperature control section from the plurality of thermal shield plates and the object if control of the temperature of the plurality of thermal shield plates and the object is completed.
