Noise and zero point drift in 1.7 mu m cutoff detectors forSNAP

PDF Version Also Available for Download.

Description

We present the results of a detailed study of the noiseperformance of candidate NIR detectors for the proposed Super-NovaAcceleration Probe. Effects of Fowler sampling depth and frequency,temperature, exposure time, detector material, detector reverse-bias andmultiplexer type are quantified. We discuss several tools for determiningwhich sources of low frequency noise are primarily responsible for thesub-optimal noise improvement when multiple sampling.The effectivenessof reference pixel subtraction to mitigate zero point drifts isdemonstrated, and the circumstances under which reference pixelsubtraction should or should not be applied are examined. Spatial andtemporal noise measurements are compared, and a simple method forquantifying the effect of hot pixels and ... continued below
