SLAC Clean Room

SLAC National Accelerator Laboratory celebrated completion of the LSST camera assembly clean room on May 8. The clean room is necessary for assembly of the LSST camera because any dust settling on the image sensors would degrade the quality of the precision device. The air inside the new facility is about 1,000 times “cleaner” than ordinary air. The main 1,875 square foot work space has a ceiling height of 24 feet to allow the approximately 10-feet-long camera body to be mounted vertically for optical alignment and final testing.

“The completion of the clean room is a big milestone for the lab,” said LSST Director Steven Kahn. “It’s the first major piece of LSST infrastructure here at SLAC.”

The DOE laboratory is responsible for providing the LSST’s 3.2 gigapixel digital camera. Assembly of the camera will occur over the next four years.

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.
