Brookhaven completes LSST’s digital sensor array

Full Text:

After 16 years of dedicated planning and engineering, scientists at the U.S. Department of Energy’s (DOE) Brookhaven National Laboratory have completed a 3.2 gigapixel sensor array for the camera that will be used in the Large Synoptic Survey Telescope (LSST), a massive telescope that will observe the universe like never before. The digital sensor array is composed of about 200 16-megapixel sensors, divided into 21 modules called “rafts.” Each raft can function on its own, but when combined, they will view an area of sky that can fit more than 40 full moons in a single image. Researchers will stitch these images together to create a time-lapse movie of the complete visible universe accessible from Chile. Currently under construction on a mountaintop in Chile, LSST is designed to capture the most complete images of our universe that have ever been achieved. The project to build the telescope facility and camera is a collaborative effort among more than 30 institutions from around the world, and it is primarily funded by DOE’s Office of Science and the National Science Foundation.
