Thermal Qualification of the Sciamachy Passive Cryogenic Cooler 1999-01-2084

This paper describes the design and qualification of this SCIAMACHY Radiant Cooler and focuses on the methods and results of the thermal balance and thermal verification test of the Radiator Reflector Unit flight model, performed late summer 1998.
A new type of temperature control has been used that proved to increase speed, simplicity and accuracy of the test itself as well as the evaluation afterwards.
The RRU TB/TV test was successful in gathering all significant thermal parameters.
After refurbishment of the cooler door and a requalification test of its transient performance all cooler parameters are acceptable and its thermal performance is within specification.
