Abstract
We have constructed a large-format mosaic CCD camera for the Sloan
Digital Sky Survey. The camera consists of two arrays, a photometric
array that uses 30 2048 x 2048 SITe/Tektronix CCDs (24 μm pixels)
with an effective imaging area of 720 cm^2 and an astrometric array that
uses 24 400 x 2048 CCDs with the same pixel size, which will allow us to
tie bright astrometric standard stars to the objects imaged in the
photometric camera. The instrument will be used to carry out photometry
essentially simultaneously in five color bands spanning the range
accessible to silicon detectors on the ground in the
time-delay-and-integrate (TDI) scanning mode. The photometric detectors
are arrayed in the focal plane in six columns of five chips each such
that two scans cover a filled stripe 2.5d wide. This paper presents
engineering and technical details of the camera.
