Closing status of the Fast TracKer system — •Marta Czurylo and André Schöning for the ATLAS collaboration — Heidelberg Universität, Germany

The Fast TracKer (FTK) system for the ATLAS detector is presented. FTK was a system designed to process hits of the silicon Inner Detector (ID), and to provide full tracking information at the High Level Trigger on events first accepted at the Level-1 trigger. FTK should have allowed to significantly reduce the computing load necessary to perform tracking over the full ID volume compared to the CPU-based tracking.

Progress achieved during the LHC Long Shutdown 2 (LS2) including the hardware and software status of the system at the time of closure as well as the most recent tracking performance analysis based on the collected data from the partially running system will be discussed. Experience from the FTK project provided important input to the design of the new "Hardware Tracking for the Trigger" project, an FTK follow up project for the High-Luminosity LHC.
