Description
The Dark Energy Survey (DES) makes use of a new camera, the Dark Energy Camera (DECam). DECam is a 570 Megapixel CCD camera covering a 3 square degree field and will be installed in the Blanco 4M telescope at Cerro Tololo Inter-American Observatory (CTIO). The camera is presently undergoing final testing at Fermi National Accelerator Laboratory and will be ready for observations in the fall of 2011. The focal plane is 1 meter in diameter and will make use of 62 red-sensitive 2kx4k fully depleted Charge-Coupled Devices (CCDs), as well as 12 2kx2k CCDs used for guiding, alignment and focus. The data acquisition system has been designed to read out images in 17 seconds with less than 15 e¯ rms noise. This poster will describe the readout system.
