The Dark Energy Survey (DES) Collaboration will study the accelerating expansion of the universe. To perform the 5000-square-degree wide field and 30-square-degree supernova surveys, the collaboration designed and built the Dark Energy Camera (DECam), a 3-square-degree, 570-megapixel charge-coupled-device (CCD) camera. During 2011 and 2012, DECam was installed on the Blanco 4-m telescope at the Cerro Tololo Inter-American Observatory (CTIO) near La Serene, Chile. Funding of the camera construction came primarily from the U.S. Department of Energy, with significant contributions from the collaborating institutions. Funding for operations of CTIO is provided by the National Science Foundation. The survey commenced in August 2013 and is expected to take 525 nights over 5 years to complete. DECam is available for use by the U.S. astronomy community when it is not allocated to the Dark Energy Survey.
