    Next generation Astrophysics Science Missions seek to interrogate the Far-IR and X-ray wavelengths requiring ADR cooled detectors to 100 mK or less. Operation of these ADR systems requires efficient thermal rejection at 4-5 K coupled with observatory cooling needs at 4-5 K and parasitic load interception at nominally 20 K. One example is the ESA Athena Mission that focuses on X-ray...

    Contributed Oral

    To mature the cryocooling system for the Probe far-Infrared Mission for Astrophysics (PRIMA) mission concept, a closed-loop JT stage using flight-like residual hardware from the JWST program was assembled to assess its cooling capacity at 4.5 K. The performance of the JT stage over a range of heat sink temperatures and system pressures was characterized. The paper presents test results without...
