We have constructed a large format mosaic CCD camera for the Sloan DigitalSky Survey. The camera consists of two arrays, a photometric array which uses30 2048 x 2048 SITe/Tektronix CCDs (24 micron pixels) with an effective imagingarea of 720 square cm, and an astrometric array which uses 24 400 x 2048 CCDswith the same pixel size, which will allow us to tie bright astrometricstandard stars to the objects imaged in the photometric camera. The instrumentwill be used to carry out photometry essentially simultaneously in five colorbands spanning the range accessible to silicon detectors on the ground in thetime-delay- and-integrate (TDI) scanning mode. The photometric detectors arearrayed in the focal plane in six columns of five chips each such that twoscans cover a filled stripe 2.5 degrees wide. This paper presents engineeringand technical details of the camera.
