Next generation in very large InSb arrays: ALADDIN, the 1024x1024 InSb focal plane array readout evaluation results

The present state of the art for scientific InSb focal planes is the Santa Barbara Research Center (SBRC) 256 X 256 device. In this paper we will present the status of the 1024 X 1024 focal plane development effort, technical details on the design, and both warm and cryogenic test data on the readout multiplexer. As the largest InSb infrared hybrid focal plane in development, this information should be of great interest to many groups. The current status and test data are presented here so that those planning future space instrumentation projects can be brought up to date on this advanced technology.
