Paper Abstract

The status of a technology program to evaluate existing infrared detector arrays and to develop improved ones for low-background astronomical applications is described. For applications such as the Shuttle Infrared Telescope Facility (SIRTF), arrays that cover as much of the 1-1000 μm range as possible are of interest. Low-background test results for 2 x 64 Si:Bi charge-injection-device and 1 x 20 InSb charge-coupled-device arrays are included. As a result of our testing, we plan to develop improved, astronomy-optimized extrinsic silicon arrays in both linear and area formats. Efforts to develop accumulation-mode MOSFETs specifically for liquid helium temperatures, and cryogenic amplifier and multi-plexer circuits, are discussed.
