Testing in Tucson

July 13, 2017 - Critical work has been underway in the lab at LSST’s Project Office in Tucson, AZ: testing of the static supports for LSST’s Primary/Tertiary Mirror (M1M3). When the 8.4-meter mirror is not under active support by the pneumatic actuators, it will rest on an array of wire rope isolators (also referred to as static supports). 355 of these supports will be installed on the mirror cell deck plate. The supports are designed to safely support the mirror under gravity and seismic loading while limiting the motion of the mirror to safe levels.

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).
