Development of innovative cryogenic test chambers

As part of a cooperation project with an industry partner a high-performance material test chamber was developed and built, which operates in a temperature range from -180 °C to +200 °C (-292 °F to 392 °F). Different methods and components were investigated, to achieve an optimal adaptation of test chambers for the intended use. As a result of the project the advantages and disadvantages of different materials and installation systems were identified and evaluated to ensure the most efficient operation and, above all, corresponding with all technical requirements. These requirements relate to:

  • the spatial and temporal distribution and stability of temperature  within a range of less than ± 1 K,
  • a safe supply and disposal of all media (refrigerant, heat, electricity, gas) and
  • a flexible design of the sample geometry as possible, with at the same time possibly less influence on the performance of the chamber system at cooling rates from 0 to 30 K/min.

The applications of such chambers are located mainly in the field of aviation and space technology, but also in highly sensitive electronic applications that are exposed to high thermal stresses.
