Abstract

Tracking detectors are devices to measure and reconstruct the trajectories of charged particles. They are developed for and used by experiments in the fields of nuclear physics, particle physics, and astro-particle physics. To understand and analyze the physics processes under study at these experiments, the reconstruction and precise determination of all particle flight paths of each event is important. From these tracks, parameters such as the particle momentum, the particle type, its origin, etc., can be deduced. Several detector technologies have been invented and are being constantly improved. The most important ones are various types of gaseous detectors, detectors based on semiconductor material, and scintillation detectors. In a realistic experiment, several tracking (and other) devices are arranged to a complex setup. Charged particle tracks are reconstructed by making use of all available information from all tracking detectors. The actual reconstruction of events from raw measurements is a nontrivial task involving pattern recognition and track and vertex fitting. The performance of both hardware and software must be optimized for the benefit of follow-on physics analyses.
