“…The cryostat consists in a Russian-doll type cryostat, with a surrounding vessel, and several concentrically suspended radiation shields, a thermally/mechanically optimized suspension system, an optical baffle, and a low temperature (2 K) structure to hold the Focal Plane Array and the sub-Kelvin cooler. Currently, cryocooler developments in Europe have enabled the possibility of a complete cooling chain, with coolers being developed at AL [7], [8], CEA [9], RAL [10] and Airbus DS UK [11]. In parallel, different cryogenic technologies for the cryostat have been developed, such as the cryogenic harness and the MLI, from previous cryogenics programs, like Herschel.…”

The TES (Transition Edge Sensors) micro-calorimeter detector technology in the X-IFU instrument for ATHENA (Astrophyics of the Hot and Energetic universe -Europe's next generation X-ray observatory ATHENA) will require cooling down to 50 mK, and a stable and quiet Electro-Magnetic and micro-vibrations environment. In order to achieve this temperature and environment, a cooling chain integrated in a compact cryostat with an optimized electromagnetic environment has to be developed. Critical technology developments are covered, such as mechanical cryocoolers, support structures, radiative and EMC shields, micro-vibrations reduction, and others.

A number of future European Space Agency (ESA), science missions may require detector cooling to sub-Kelvin temperatures. One such mission is the X-ray Evolving Universe Spectroscopy (XEUS), mission, which is a candidate for the ESA Cosmic Vision 2015-2025 plan, following XMM-Newton and Chandra. The Detector Spacecraft model payload comprises a passively cooled wide-field camera at 200K, and one of two narrowfield instruments at 300mK and 50mK. As with several other science missions, the required lifetime is at least 5 years, with a 10 year goal, necessitating the use of long-life closed cycle cooling systems. Under contract to ESA, Astrium has worked with the Mullard Space Science Laboratory (MSSL), Rutherford Appleton Laboratory (RAL), and CEA-SBT, to propose a payload accommodation design for XEUS capable of meeting the demanding requirements. Our baseline consists of a two stage Adiabatic Demagnetization Refrigerator (ADR), at 50mK, and a helium sorption cooler at 300mK. Each system will be pre-cooled by a closed cycle J-T system, similar to Planck, at 2.5K or 4K, which itself will be precooled by a two-stage Stirling cycle cooler, at 17K or 18K. This paper describes the mission, and discusses the cryogenic architectures in depth.
