ITL Completes LSST Sensors Contracts

The University of Arizona has completed delivery of over 100 science-grade 4kx4k Charge-Coupled Device (CCD) image sensors for the Large Synoptic Survey Telescope (LSST). This work was performed at the UA Imaging Technology Laboratory (ITL). The sensors are among the most demanding ever produced in terms of quantum efficiency, readout speed, and surface flatness. ITL had previously delivered a set of 4kx2k wavefront sensors which will also be used in the LSST focal plane. Both sensors were designed by Semiconductor Technology Associates, Inc. in California. The Imaging Technology Laboratory is directed by Dr. Michael Lesser and is a research group within the University's Steward Observatory. Financial support for LSST comes from the National Science Foundation (NSF) through Cooperative Agreement No. 1258333, the Department of Energy (DOE) Office of Science under Contract No. DE-AC02-76SF00515, and private funding raised by the LSST Corporation. The NSF-funded LSST Project Office for construction was established as an operating center under management of the Association of Universities for Research in Astronomy (AURA). The DOE-funded effort to build the LSST camera is managed by the SLAC National Accelerator Laboratory (SLAC).
