Description
Tracking devices are the tool to reconstruct the trajectories of charged particles and play a central role in the reconstruction of whole events in complex multi-purpose detectors. Excellent tracking is crucial for many physics analysis at the LHC, e.g. the identification of b-quarkjets typically utilises tracking information. To optimise the performance of tracking systems, one has to study the properties of different materials with as little uncertainties as possible. One important systematic uncertainty are possible displacements and rotations of the detector modules leading to biases and degraded resolution in the track fit.
This presentation gives an overview on tracking in general and at the example of the General Broken Lines track fit followed by an introduction into track-based alignment procedures as
they are used in test beams, but also in large-scale experiments at the LHC.
