Abstract

The Dark Energy Survey Camera (DECam), when completed, is going to have one of the largest existing focal planes, equipped with more than 70 CCDs. Due to the large number of CCDs and the tight space on the camera, the DECam electronics group has developed new compact front-end electronics capable of flexibly and rapidly reading out all the focal plane CCDs. The system is based on the existing MONSOON Image Acquisition System designed by the National Optical Astronomy Observatory (NOAO), and it is currently being used for testing and characterization of CCDs. Boards for the new readout are being developed in USA and Spain, with the first prototypes already produced and tested. The next version with some improvements will be tested during 2008 and the system will be ready for production at the beginning of 2009. Custom MONSOON boards and the electronics path will be described.
