	The Thermal Contact Conductance (TCC) between two surfaces plays a very important role in the design of components in particle accelerators. The TCC depends on many variables such as surface finish, type of material, pressure, temperature, etc. As a general rule, the TCC comes from experimental results reported in the specialized literature. However, it is not always possible to find this information, especially if components are designed to operate in cryogenic and vacuum conditions, for this reason, assumptions are made that render results with high uncertainty. In this context, ALBA has designed an experimental set up to carry out axial heat flow steady state experiments for the evaluation of TCC under vacuum and cryogenic conditions. The minimum pressure achievable in the set up will be 1e-5 mbar while the temperature may vary between 80 and 300 K. The results will provide inputs to further optimize ALBA designs, including ALBA II, our ongoing fourth-generation synchrotron upgrade project. This paper describes the experimental setup, the thermal and mechanical design considerations and experimental validation tests.
