The Sloan Digital Sky Survey: Technical Summary
The Sloan Digital Sky Survey (SDSS) will provide the data to support detailed
investigations of the distribution of luminous and non- luminous matter in the
Universe: a photometrically and astrometrically calibrated digital imaging
survey of pi steradians above about Galactic latitude 30 degrees in five broad
optical bands to a depth of g' about 23 magnitudes, and a spectroscopic survey
of the approximately one million brightest galaxies and 10^5 brightest quasars
found in the photometric object catalog produced by the imaging survey. This
paper summarizes the observational parameters and data products of the SDSS,
and serves as an introduction to extensive technical on-line documentation.Comment: 9 pages, 7 figures, AAS Latex. To appear in AJ, Sept 200
A high-rate fastbus silicon strip readout system
This paper describes a synchronous silicon S ~rePado ut system capable of zero deadtime readout at average trigger rates in excess of 1 MHz. The system is implemented in FASTBUS, uses pipelining techniques, and includes p6nt-Wpoint fiberoptic data links to transmit detector digital data. Semi-custom ASIC chips are used to amplify, discriminate, and logically combine track data before encoding. This paper describes the overall system, each major FASTBUS module, and the functional aspects of the ASIC chips
