The ATLAS FastTracker

Though hardware-based trackers were a crucial element of the triggering systems for both D0 and CDF, no such system has yet been incorporated into either ATLAS or CMS. The ATLAS FastTracKer (FTK) is a first step towards this goal, and will soon provide full tracking information for all events passing ATLAS’s Level-1 trigger. This system massively reduces the CPU required to identify track-based signatures like b-jets and taus, and allows for the suppression of pile-up effects on missing energy and jet triggers. This talk will present an overview of FTK commissioning and future plans, along with updated projections for FTK performance.
