First Science Raft Tower Module Completed!

December 9, 2016 - The Science Raft team, located primarily at Brookhaven National Laboratory (BNL), has constructed the very first Science Raft Tower Module populated with a full array of 9 CCDs and 3 Raft Electronics Boards (REBs).  The Raft is an Engineering Test Unit (ETU1), which was assembled for design and construction validation purposes and will be used to support commissioning efforts at Test Stand 8 where a full suite of electro-optical tests will be performed at the Raft level.  The Raft Sensor Assembly (RSA) for this ETU was already leveraged to commission Test Stand 5, where warm and cold RSA metrology is performed at temperatures as low as -100oC.

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).
