A high luminosity trigger design

In this paper, the authors describe the triggering system for the DO Experiment at the Tevatron proton-antiproton collider. In Section II we give an overview of the structure of the trigger and data acquisition systems with particular attention to the principal signal paths. The Calorimeter Trigger is described in Section III and in Section IV, the authors discuss some of the Monte Carlo studies that were done to study the trigger performance and determine its design parameters. They end with a summary of their current status in Section V and acknowledgement of support in Section VI
