Patent ID: 8756941

Claim:
A cryogenic apparatus, comprising: a nested thermally insulated structure for holding a sample to be cooled; a cryo-cooler; and a thermal link connecting the nested thermally insulated structure and the cryo-cooler, wherein the nested thermally insulated structure comprises: a sample chamber for containing the sample to be cooled; a sample mount having an upper surface and a lower surface; a first tube coupler; a second tube coupler; an inner thermally insulated tube attached to the lower surface of the sample mount; and an outer thermally insulated tube attached to the inner thermally insulated tube via the first tube coupler and the second tube coupler, wherein: the sample chamber is disposed on a side of the sample mount opposite the inner and outer thermally insulated tubes, the upper surface of the sample mount forms a base of the sample chamber, a top portion of the sample chamber is disposed opposite the upper surface of the sample mount, a radial tube portion of the sample chamber connects the upper surface of the sample mount and the top portion of the sample chamber, and the outer thermally insulated tube surrounds the inner thermally insulated tube such that a point midway between the top and bottom of the inner thermally insulated tube is disposed between the top and bottom of the outer thermally insulated tube.
