Cutting-Edge ADR Systems Enable Ultra-Low Temperature Cooling for High-Precision Space Detectors

The ETD Cryogenics and Fluids team is the home of leading experts in spaceflight Adiabatic Demagnetization Refrigeration Systems (ADR) worldwide. Our ADR systems have proven to provide sustained cooling to spaceflight detectors as low as 30 mK for missions such as the X-Ray Imaging and Spectroscopy Mission (XRISM). These magnetic refrigeration systems, which consist of parts predominantly fabricated and assembled by Goddard Space Flight Center personnel, are a favored option for Sub-Kelvin detector projects that require negligible vibrational input.

The Adiabatic Demagnetization Refrigeration System (ADR) capability is managed by ETD’s
Instrument System and Technology Division (ISTD). Contact ISTD for more information.
