The general purpose DØ collider detector, located at Fermi National Accelerator Laboratory is operated in the high luminosity (L = 2 × 10 32cm-2s-1) and high collision rate environment (396 ns between beam crossings) of the upgraded Tevatron proton anti-proton accelerator. DØ uses a three tiered trigger system to select events for offline storage and analysis. This talk describes the architecture and performance of the DØ 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.
