Abstract
A vertical support rigidly mounted to a planar base positions and supports a cryocooler expander unit off axis and away from a sample to be examined. The sample support is likewise rigidly mounted to the planar base with a rigidly mounted sample housing therein. The cryocooler expander unit is suspended in the vertical support by spring dampening bearings. A pair of opposing flexible vacuum bellows connects the cryocooler expander unit to the sample housing and vertical support. This configuration isolates the sample from vibration. Flexible thermal links associated with a predictive electronic closed loop control sequence maintains sample temperature.

A conductive bundle of flexible thermal links extending between a heat conductive arm and a thermal sample support of an apparatus for low temperature microscopy and/or spectroscopy, the bundle comprising a plurality of links, each individual link of the plurality extending from a first end to a second end, wherein the first ends of the links are coupled to one another and the second end of the links are also coupled to one another to form the conductive bundle.
A conductive bundle of flexible thermal links extending between a heat conductive arm and a thermal sample support of an apparatus for low temperature microscopy and/or spectroscopy, the bundle comprising a plurality of copper links, each individual link of the plurality extending from a first end to a second end, wherein the first ends of the links are coupled to one another and the second end of the links are also coupled to one another to form the bundle.
A method for preparing a conductive bundle of flexible thermal links that are to be used to extend between a heat conductive arm and a thermal sample support of an apparatus for low temperature microscopy and/or spectroscopy, the method comprising:
- providing a plurality of individual links;
- annealing the links;
- bundling the plurality of links, each individual link of the plurality extending from a first end to a second end, the bundling comprising coupling the first ends to one another and coupling the second end of the links to one another;
- and
- affixing the bundle between the heat conductive arm and the thermal sample support.
