Document Type and Number:
WIPO Patent Application WO/2019/073971
Kind Code:
A1
Abstract:
A mounting structure for a cryogenic refrigerator 10, said mounting structure comprising: a sleeve 16; a flange interval adjustment mechanism 18 for adjusting an interval between a sleeve-side flange 50 and a cold-head-side flange 34 so as to physically bring into contact or separate a cold-head-side cooling stage 32 and a sleeve-side cooling stage 48, while keeping an airtight region 28 isolated from the surrounding environment 26; and a flange fastening mechanism 20 for fastening the cold-head-side flange 34 to the sleeve-side flange 50 so as to press the cold-head-side cooling stage 32 against the sleeve-side cooling stage 48 with a prescribed pressing surface pressure such that the cold-head-side cooling stage 32 and the sleeve-side cooling stage 48 are in thermal contact with a thermal resistance of a value equal to or less than a threshold value.
