Description
The e2v and ITL CCDs used in Rubin Observatory's LSST-CAM are tested under realistic LSST f/1.2 optical beam in a lab setup. In the past this facility has been used to characterize these CCDs, exploring the systematic errors due to charge transport. Now this facility is being used to optimize the clocking scheme and voltages. The effect of different sequencers on the on-chip systematics such as non-linear crosstalk, noise, tearing, persistence, photon transfer, etc are explored. The goal is to converge on an optimal configuration for the LSST-CAM CCDs which minimizes resulting dark energy science systematics.
