Abstract: 
The Large Synoptic Survey Telescope (LSST) camera will be made as a mosaic assembled of 189 large format Charge Coupled Devices (CCD). They are n-channel, 100 micron thick devices operated in the over depleted regime. There are 16 segments, 1 million pixels each, that are read out through separate amplifiers. The image quality and readout speed expected from LSST camera translates into strict acceptance requirements for individual sensors. Prototype sensors and preproduction CCDs were delivered by vendors and they have been used for developing test procedures and protocols. Building upon this experience, two test stands were designed and commissioned at Brookhaven National Laboratory for production electro-optical testing. In this article, the sensor acceptance criteria are outlined and discussed, the test stand design and used equipment are presented and the results from commissioning sensor runs are shown. © (2016) COPYRIGHT Society of Photo-Optical Instrumentation Engineers (SPIE).

Financial support for Rubin Observatory 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 Rubin Observatory 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 Rubin Observatory LSST Camera (LSSTCam) is managed by the SLAC National Accelerator Laboratory (SLAC).
The National Science Foundation (NSF) is an independent federal agency created by Congress in 1950 to promote the progress of science. NSF supports basic research and people to create knowledge that transforms the future.
NSF and DOE will continue to support Rubin Observatory in its Operations phase. They will also provide support for scientific research with LSST data.
