Title: "The Dark Energy Survey instrument: the Dark Energy Camera"

Abstract:

The Dark Energy Survey will measure the dark energy equation of state using four techniques: galaxy cluster counts; weak lensing; baryon acoustic oscillation; supernova Hubble diagram. The 500 mega-Pixel Dark Energy Camera will produce 300 Gigabytes of data a night. The Dark Energy Survey will use the camera to image 5,000 square degrees of the sky. The camera will also be available for astronomers using the Blanco 4-meter telescope.
