“…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.…”

ATHENA X-IFU detector cooling chain

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.
