Tracking detectors play a major role in nuclear and particle physics. They provide a full image of particle trajectories in various medias. There are gaseous ionization detectors (e.g. wire chambers, drift chambers, micropattern gaseous detectors) and solid‐state detectors (e.g. silicon pixel, strip, and drift detectors). Normally, a combination of detectors must be used in tracking systems, for example, large‐volume time projection chambers and silicon trackers.
