Paper Abstract

Large-area near-infrared focal-plane detector arrays constructed from one and four Rockwell Science Center HAWAII- 2RG HgCdTe detectors have been characterized for use in the NIFS and GSAOI instruments recently developed for the Gemini telescopes by the Australian National University. We present details of the detector characterization and compare the performance of five distinct devices with respect to read noise, dark current, and stability in systems based on ARC/SDSU Gen-3 controllers. Advanced operating modes of the H2RG were implemented including enhanced clocking and independent On-Detector Guide Windows for GSAOI. Detector performance using these features and the impact of multiple guide-window reads on long integrations are explored. We also discuss measurement of intra-pixel coupling and its impact on pixel-well capacity, gain, and image quality for these devices.
