Title: Effects of various event building techniques on data acquisition system architectures

Abstract

The preliminary specifications for various new detectors throughout the world including those at the Superconducting Super Collider (SSC) already make it clear that existing event building techniques will be inadequate for the high trigger and data rates anticipated for these detectors. In the world of high-energy physics many approaches have been taken to solving the problem of reading out data from a whole detector and presenting a complete event to the physicist, while simultaneously keeping deadtime to a minimum. This paper includes a review of multiprocessor and telecommunications interconnection networks and how these networks relate to event building in general, illustrating advantages of the various approaches. It presents a more detailed study of recent research into new event building techniques which incorporate much greater parallelism to better accommodate high data rates. The future in areas such as front-end electronics architectures, high speed data links, event building and online processor arrays is also examined. Finally, details of a scalable parallel data acquisition system architecture being developed at Fermilab are given. 35 refs., 31 figs., 1 tab.
