Abstract

The small helium cooled infrared telescope for Spacelab 2 will permit sensitive mapping of extended, low-surface-brightness celestial sources as well as highly sensitive investigations of the shuttle contamination environment. The development of the focal plane array for this instrument is described. A number of the Photoconductive detectors used in the focal plane were made at the University of Arizona, and we describe the fabrication procedure and some test results. A design for a thermally isolated, self-heated J-FET transimpedance amplifier is presented. This amplifier is Johnson noise limited for feedback resistances from less than 10 8 Ω to greater than 2 x 10 10 Ω at T = 4.2K. Work on the focal plane array is now complete. Performance testing for qualification of the flight hardware is discussed, and results of this work are presented. All infrared data channels are measured to be background limited by the expected level of zodiacal emission.
