Abstract

Raytheon Infrared Operations is under contract to develop 2K x 2K InSb arrays for the NGST NIRcam instrument and 1K x 1K Si:As IBC arrays for the NGST MIRI instrument. This paper reviews the progress in the NIR, showing NGST bare mux readout noise at 30 K of 2.4 e- and InSb dark current as low as 0.02 e-/s. Detectors and readouts have been fabricated in the 2K x 2K format and, except for adding indium bumps to the readouts, are ready for hybridization. Module and FPA designs are complete, resulting in a design that has self-aligning, interchangeable modules and requires no additional cold electronics to perform the NGST mission. Analysis predicts an alignment accuracy in the focus direction of ± 12 μm and total power for a 4K x 4K focal plane of 5 mW.
