Paper Abstract

We present characterization methods and results on a number of new devices produced specifically to address LSST's performance goals, including flatness, QE, PSF, dark current, read noise, CTE, cosmetics, and crosstalk. The results indicate that commercially produced, thick n-channel over-depleted CCDs with excellent red response can achieve tight PSF at moderate applied substrate bias with no evidence of persistent image artifacts. We will also report ongoing studies of mosaic assembly techniques to achieve chip-to-chip co-planarity, high fill factor, and thermal stability.
