Vera C. Rubin Observatory, as a Federal Government funded project, is operating in compliance with the
Presidential Executive Order on Ensuring Adequate COVID Safety Protocols for Federal Contractors.
The LSST Camera's focal plane is the area across which light from the telescope's mirrors, further corrected by the telescope's lenses, comes to a focus. As such the focal plane is the heart of the camera, responsible for capturing the light from billions of distant galaxies in a form that can be preserved.
The array of charge-coupled device (CCD) sensors in the camera's focal plane operates at a temperature of approximately -100°C to achieve desired detector performance. The focal plane array is housed in an evacuated cryostat, which includes front-end electronics and thermal control for the detector array. The cryostat lens serves as both light entrance window and vacuum seal for the cryostat.
Similarly, the camera body lens serves as an entrance window and gas seal for the camera housing, which is filled with dry nitrogen gas to provide an operating environment for the shutter and filter change mechanisms. The filter carousel can accommodate five filters, each 75 cm in diameter, and the filters can be swapped out robotically in two minutes or less.
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.
