Abstract

The Sloan Digital Sky Survey (SDSS) will image {Pi} steradians about the north galactic cap in five filters, and acquire one million spectra using a dedicated 2.5 meter telescope at the Apache Point Observatory in New Mexico. The authors describe the data acquisition system for the survey`s three main detectors: an imaging camera, mounting 54 Tektronix charge-coupled devices (CCD); a pair of spectrographs, each mounting a pair of CCDs; and a smaller monitor telescope camera. The authors describe the system`s hardware and software architecture, and relate it to the survey`s special requirements for high reliability and need to understand its instrumentation in order to produce a consistent survey over a five year period.
