Nearly all cryogenic engineering experiments and applications Involve heat transfer problems. Heat sinking is generally concerned with either of two extremes: (1) maximum thermal isolation or (2) maximum heat dissipation. To attain these objectives requires careful attention to the selection of materials, and the design of components and the overall system. For example, in the operation of an adlabatic calorimeter system in the measurement of the specific heat or enthalpy of a material In the cryogenic temperature range, extraneous heat flows of the order of microwatts may be sufficient to vitiate the experiment, Other experiments call for the effective dissipation of any heat which may be transferred to the device by power or signal leads or may be generated In the device itself. The thermal grounding must generally be accomplished without electrically grounding or shorting the components.
