Measurement of Thermal Properties at Low Temperatures

The cool down to cryogenic temperature causes thermal stress within the structure of components or complete devices. Furthermore thermal material properties could change crucial.

Samples can be proved down to 10 K via temperature cycling tests and/or measurements of the thermal conductivity, the coefficient of thermal expansion (also as integral for large sample dimensions) and the heat capacity. An experimental station with optimised conditions for measuring the thermal conductivity of different materials is under construction.
