Preliminary design of a 1.8 K thermal conductivity test stand for HFM

This document presents the work developed at the Central Cryogenic Laboratory (Cryolab) during the 2023 Summer Students Programme, which focused mainly on the preliminary design of a 1.8 K thermal conductivity test stand for the HFM programme. The main goals of the 1.8 K test stand and its relationship with the HFM programme will be introduced, followed by the description of the system and each component's design process. The system's instrumentation diagram will be presented and the next steps will be discussed. Finally, the description of other works developed at Cryolab during the programme will be commented.
