Abstract

A 256 X 256 element InSb (indium antimonide) focal plane array has been specifically developed for use in ground-based astronomy. The array is an indium bump hybrid of a high- quality InSb detector array fabricated with an improved process, mated to a new, specially- designed low-background multiplexer. The performance parameters have been tuned to best reflect the requirements of ground based astronomy. The circuit is a direct readout detector integrator. It has a well size typically around 1,000,000 electrons, a readout rate of about 400 kHz, and has an expected noise level of about 200 electrons.
