A Hardware Track Finder for ATLAS Trigger
The existing three level ATLAS trigger system is deployed to reduce the event rate from the bunch crossing rate of 40 MHz to ~400 Hz for permanent storage at the LHC design luminosity of 10^34 cm^-2 s^-1. When the LHC reaches beyond the design luminosity, the load on the Level-2 trigger system will...

| description | The existing three level ATLAS trigger system is deployed to reduce the event rate from the bunch crossing rate of 40 MHz to ~400 Hz for permanent storage at the LHC design luminosity of 10^34 cm^-2 s^-1. When the LHC reaches beyond the design luminosity, the load on the Level-2 trigger system will significantly increase due to both the need for more sophisticated algorithms to suppress background and the larger event sizes. The Fast TracKer (FTK) is a custom electronics system that will operate at the full Level-1 accepted rate of 100 KHz and provide high quality tracks at the beginning of processing in the Level-2 trigger, by performing track reconstruction in hardware with massive parallelism of associative memories and FPGAs. The performance in important physics areas including b-tagging, tau-tagging and lepton isolation will be demonstrated with the ATLAS MC simulation at different LHC luminosities. The system design will be overviewed. The latest R&D progress of individual components will be presented and related technologies will be discussed. |
