Abstract
The general purpose DO collider detector, located at Fermi National Accelerator Laboratory, is operated in the high luminosity (L = 2 X 10(32) cm(-2) s(-1)) and high-collision-rate environment (396 ns between beam crossings) of the upgraded Tevatron proton anti-proton accelerator. DO uses a three-tiered trigger system to select events for offline storage and analysis. This paper describes the architecture and performance of the DO central track trigger (CTT) system based on the new central fiber tracker, central preshower and forward preshower detectors, with emphasis on the interface to and integration with the second tier L2 Trigger system.
