AVS is developing the flight cryostat design for the X-IFU instrument of ESA's ATHENA mission. This cryogenic system is responsible for supporting and integrating the instrument's cold core, whose operation depends on its ability to reach 50 mK. The design of this component presents multiple technical and manufacturing challenges as well as multiple trade-offs to manage i.e. thermal conductivity, mechanical resistance, weight, etc. This work shows the efforts made by AVS in order to create and evaluate a first cryostat architecture capable of satisfying thermal, mechanical, manufacturability and high-level assembly requirements. This work has been carried out in the framework of an ESA PRODEX contract.
