The Dark Energy Survey Collaboration will perform a 5000 sq-deg survey of the southern sky and use the data to constrain the dark energy equation of state. In order to perform the survey, it is building the Dark Energy Camera, which will be an NOAO community instrument [39] for the 4m Blanco Telescope at Cerro Tololo. DECam construction is nearly complete. Integration and commissioning on a "telescope simulator" of the major hardware and software components, except for the optics, recently concluded at Fermilab. Most components have been received at CTIO. The SISPI computers, F/8 handling system and LN2 cooling system have been installed. The filter-changer, shutter, and hexapod arrived safely and have been retested there. The imager itself is being held at Fermilab until CTIO is ready for it (expected during October 2011). The optical corrector will be the last part to be shipped to CTIO, arriving during November of this year (2011). First light will be in 2012. The Dark Energy Survey is expected to start in September 2012.
