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.
Claims11
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 adjacent links, each individual link of the plurality extending from a first end to a second end, wherein the first ends of the links extend and are coupled to one another to form a first flange and the second ends of the links extend and are also coupled to one another to form a second flange, single empty spaces being defined between the individual adjacent links to form the conductive bundle having a plurality of continuous single empty spaces without interruption between the plurality of adjacent links and between the first and second flanges, wherein the first flange is coupled to the heat conductive arm and the second flange is coupled to the thermal sample support.
The conductive bundle of claim wherein each of the individual adjacent links define upper and opposing lower surfaces with edges extending between the surfaces, the individual adjacent links being stacked above each other within the bundle to provide a lower surface of one link opposing the upper surface of an adjacent link.
