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.
