The Dark Energy Camera (DECam) is the new wide field prime-focus imager for the Blanco 4m telescope at CTIO.This instrument is a 2.2 sq. deg. camera with a 45 cm diameter focal plane consisting of 62 2k × 4k CCDs and 12 2k × 2kCCDs and was developed for the Dark Energy Survey that will start operations at CTIO in 2011. DECam includes thevessel shell, the optical window cell, the CCDs with their readout electronics and vacuum interface, the focal planesupport plate and its mounts, and the cooling system and thermal controls. Assembly of the imager, alignment of thefocal plane and installation of the CCDs are described. During DECam development a full scale prototype was used formulti-CCD readout tests. This test vessel went through several stages as the CCDs and related hardware progressedfrom early prototypes to final production designs.
