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.
