Abstract

Hardware and emulation results of the track finder demonstrator are presented and compared. Simulated physics events with a pileup 200 proton-proton interactions per bunch crossing are used to measure the performance of the system. Relevant quantities such as tracking efficiency, purity, rate, and parameter resolution are discussed. The robustness of the track finding to detector defects and evolving requirements is discussed. The latency and the FPGA resource utilisation of the track finding chain are measured. These metrics are compared against alternative track finding solutions.
