Cryostat Testing in Tucson

May 21, 2018 - The Auxiliary Telescope for LSST has arrived safely on the summit of Cerro Pachon, and its heaviest parts have been lifted into its enclosure building by crane. Meanwhile, in Tucson, preparations are being made for the assembly and testing of the calibration equipment that will be mounted on the Auxiliary Telescope (AT) in order to measure atmospheric transmission during LSST operations (as described in this recent news item). In early May, twenty-three shipping boxes containing the cryostat and associated peripherals arrived at the Project Office workshop in Tucson. The cryostat contains the sensor that will be used to image spectra from the AT’s spectrograph.

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).
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.
