Paper Abstract

The primary goal of the HAWAII 4RG-15 (H4RG-15) development is to provide a 16 megapixel 4096x4096 format at significantly reduced price per pixel while maintaining the superb low background performance of the HAWAII 2RG (H2RG). The H4RG-15 design incorporates several new features, notably clocked reference output and interleaved reference pixel readout, that promise to significantly improve noise performance while the reduction in pixel pitch from 18 to 15 microns should improve transimpedance gain although at the expense of some reduction in full well and possible increase in crosstalk. We report the results of very preliminary characterization of a science grade Phase 2 λc ~ 2.5 μm H4RG-15 operated in both conventional and Interleaved Reference Pixel (IRP) 32-output mode and have demonstrated that the CDS averaged read noise at 200 kHz pixel rate is comparable to, and possibly slightly below, that of the best Phase 1 H4RG-15s. We have also investigated the characteristics of pixels exhibiting RTN in the IRP frames.
