Paper Abstract

The CCD sensors that will be used in the LSST Camera are controlled using a large number of bias and clock voltages. The objective of this project is to explore the large parameter space of operating voltages and optimize the performance of the CCDs made by ITL, one of two vendors manufacturing the LSST CCDs. The CCD voltages were adjusted from their nominal operating values in small increments and the electro-optical characteristics were measured. These measurements were performed first using a single ITL sensor and later with a 3 by 3 CCD mosaic with integrated controller electronics (Raft) of engineering grade ITL sensors, using a test stand at SLAC.
