Abstrakt: The design of an engineering model ADR system to cool cryogenic detectors to 50–30 mK is presented which is designed to be cooled via a 4–5 K space cryocooler. The system will be subjected to vibration qualification suitable for an Ariane 5 launch. The ADR is of a double ADR form comprising a chromic potassium alum (CPA) low temperature stage and dysprosium gallium garnet (DGG) high temperature stage. Details of the 3 Tesla (< 2.5 Amp) magnet system and the magnetic shielding for the detector focal plane and potential spacecraft are given with modelled results. © 2004 American Institute of Physics [ABSTRACT FROM AUTHOR]
