25 September 1989 Test Chamber For Low-Background IR Focal Plane Testing
Author Affiliations +
A unique and versatile vacuum chamber has been designed and built by R.G. Hansen and Associates for the Jet Propulsion Laboratory's Infrared Focal Plane Technology Group. This chamber is equipped with multiple ports for cryogen and electrical vacuum feedthroughs, pumping units, vacuum gauges, sources, and detector camera heads. The design incorporates a liquid-nitrogen-cooled optical table and radiation shield for low-background infrared detector testing. Focal planes can be tested in this chamber at temperatures ranging from 300 K to that of liquid helium. The test chamber design emphasizes versatility so that the system can accommodate various detectors and testing conditions. This paper describes the design and construction of this low-background infrared focal plane test chamber and discusses some of its distinctive features. An analysis of the test chamber's performance is also be presented.
