A Common Tracking Software (Acts)
Latest release: v0.22.00
16 Apr 2020
Introduction
This project contains an experiment-independent set of track reconstruction tools. The main philosophy is to provide high-level track reconstruction modules that can be used for any tracking detector. The description of the tracking detector's geometry is optimized for efficient navigation and quick extrapolation of tracks. Converters for several common geometry description languages exist. Having a highly performant, yet largely customizable implementation of track reconstruction algorithms was a primary objective for the design of this toolset. Additionally, the applicability to real-life HEP experiments plays major role in the development process. Apart from algorithmic code, this project also provides an event data model for the description of track parameters and measurements.
Key features of this project include: tracking geometry description which can be constructed from TGeo, DD4Hep, or GDML input, simple and efficient event data model, performant and highly flexible algorithms for track propagation and fitting, basic seed finding algorithms.

Repository structure
The repositories for the Acts project can be found at
https://gitlab.cern.ch/acts
acts-core
The acts-core repository contains the all detector independent software that is part of the Acts toolkit.
acts-fatras
The acts-fatras repository contains the fast track simulation extension of the Acts toolkit.
The fast track simulation moduels are currently in development and available only in a limited way.
acts-data
The acts-data repository contains some necessary data files for running the standard Acts examples.
acts-framework
The acts-framework reposity contains a small event processing framework for development and testing. The framework is capable of parallel event processing if OpenMP is available on the machine.
Acts test jobs are run in the framework in the continuous integration, and tested for bit-wise identical result between single and multithreaded mode.
The acts-framework includes acts-core and acts-fatras as submodules in an external folder.
