The reconstruction of the trajectories charged particles, or track reconstruction, is a key computational challenge for particle and nuclear physics experiments. While tuning algorithms can depend strongly on details detector geometry, currently in use by experiments share many common features. At same time, intense environment High-Luminosity LHC accelerator other future expected to put even greater stress software, motivating development more performant algorithms. We present here A Common Tracking Software (ACTS) toolkit, which draws experience with ATLAS experiment presents them an experiment-independent framework-independent toolkit. It provides set high-level tools are agnostic detection technologies magnetic field configuration tested strict thread-safety support multi-threaded event processing. discuss conceptual design technical implementation ACTS, selected applications performance lessons learned.
