Summary
The cryogenic subsystem uses state-of-the-art superfluid helium dewar technology along with Stirling cycle coolers to achieve a five-year orbital lifetime with minimum system mass and size. The dewar provides a 1.5 K temperature environment for operation of the cryogenic instrument assembly, which includes an adiabatic demagnetization refrigerator for cooling the detectors to 0.1 K. Launch is planned in December 1999. The programme status, the newly baselined cryogenic subsystem design and its predicted performance are discussed.
