Paper Abstract

The James Webb Space Telescope Fine Guidance Sensor makes use of three 2048×2048 five micron cutoff HAWAII- 2RG HgCdTe detectors from Teledyne Imaging Systems. The FGS consists of two Guider channels and one Tunable Filter Imager (TFI) channel. We report here on our efforts to optimize the performance of the FGS detector sub-system consisting of the detector arrays, the Teledyne SIDECAR ASIC, and the FGS specific SIDECAR Control Electronics. The FGS-Guider has a number of unique readout modes which are required to support observatory operations, requiring different optimizations for these readout modes compared to those required for science observations with the TFI.
