Dark Energy Camera imager of the Dark Energy Survey completed

This month, Fermilab technicians and Dark Energy Survey collaborators installed the last of 62 science-quality charged coupling devices, or CCD’s, into the imager for the Dark Energy Camera [called DECam] currently housed at SiDet. CCDs work like film, and each one contains 8 million pixels. The camera also has another 12 CCDs of 4 million pixels each for guiding and focusing. The imager will head to Chile in mid-August for installation on the Blanco telescope. DES collaborators in Chile just finished installing the off-telescope components of the DECam imager liquid-nitrogen cooling system in preparation for the camera’s arrival. Photo: Reidar Hahn

Dark Energy Survey, DES, is trying to determine what is expanding the universe and how dark energy is connected to it by imaging distancing galaxies.
