Abstract

We have constructed a far infrared detector array consisting of a 1×16 Ge:Ga and a 1×16 Ge:Sb placed side-by-side to form a linear, 1×32 array. An SBRC-190 readout multiplexer, which is a 1×32, multi-gain, capacitive transimpedance amplifier (CTIA) manufactured by Raytheon Infrared Operation, is wire bonded to the array. The array has been tested in the temperature range of 3.2K to 2.6K under various infrared radiation levels. In this presentation we will discuss the design and will report on the results of the preliminary tests conducted on this array at 3.0K. This developmental effort is intended to test the viability of the SBRC-190 unit-cell design for far infrared detector arrays and help foster improvement and further development of readout electronics based on the CTIA design. In addition, we hope to extend the detector design and develop a two-dimensional, monolithic array.
