Tracking Detectors
Veröffentlicht am 30.07.2010 in pp. x01-x30 of "Handbook of Particle Detection and Imaging" (Editors: C. Grupen, I. Buvat, D. McGregor), in print at Springer-Verlag, Berlin 2011, ISBN 3-642-13270-7.

Tracking detectors are devices to measure and reconstruct the trajectories of charged particles. They are developed for and used by physics 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 the particles flight path is important. From these particle 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 the various types of gas detectors, detectors based on semiconductor material, and scintillating detectors.

In a realistic experiment, several tracking (and other) devices are arranged to a complex set-up. 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 non-trivial task involving pattern recognition, track and vertex fi tting. The performance of both hardware and software must be optimized for the bene t of follow-on physics analyses.
