Abstract
Preliminary test results from the evaluation of Si:Sb and Si:Ga 58 x 62 element infrared detector arrays are presented. These devices are being characterized under background conditions and readout rates representative of operation in orbiting cryogenically-cooled infrared observatories. The arrays are hybridized to silicon direct readout multiplexers which allow random-access and non-destructive readout. Array performance optimization is being conducted with a flexible microcomputer-based drive and readout electronics system. Preliminary Si:Sb measurements indicate a sense node capacitance of 0.06 pF, peak (28 μm) responsivity >3 A/W at 2V bias, read noise of 130 rms e-, dark current ~10 e-/s, and a well capacity >105e-. The limited test data available on the performance of the Si:Ga array are also discussed.
