Title: Engineering Tests and Initial Calibration of DECam CCDs

Abstract: We request time to perform testing and photometric calibration of the Dark Energy Survey CCDs. Specifically, we will once again deploy a direct imaging CCD system to the CTIO/Yale/SMARTS 1m telescope. The detector will be identical to the CCDs that will eventually be used in the Dark Energy Camera. The goal will be to provide initial on-sky testing of the CCD system, which tests controller and CCD properties generally and obtain early information on the photometric calibration of DES filters. We had time in April 2008 for initial testing and deployment of the system. Unfortunately, technical problem prevented any useful data collection. A second run will take place in October 2008 (just after the proposal deadline); we have upgraded the system and expect no further technical problems and substantially improved reliability.
