<P>PROBLEM TO BE SOLVED: To provide a refrigerator coupling structure for enabling attaching/detaching and re-cooling of the refrigerator in a short time-period, by suppressing a heat movement from the refrigerator at the room temperature to an object to be cooled which is cooled down to cryogenic temperature when attaching a cryogenic refrigerator thereon, while suppressing a volume of heat invasion into the object to be cooled. <P>SOLUTION: The structure includes a heat contact portion having a flexible portion at least in a part thereof, which is coupled with a cold stage of the cryogenic refrigerator 1, wherein a heat contracting ring which has a heat contraction rate larger than that of the heat contact portion is provided on the outer peripheral portion of this heat contact portion. <P>COPYRIGHT: (C)2012,JPO&INPIT |
