Difference between revisions of "Tracker"

A '''track detector''' or '''tracker''' is the part of a [[detector]] for measuring the trajectories of [[Electric charge|charged]] [[Particle|particles]]. Trajectory information is used for [[Vertex (experimental)|vertex finding]] as well as [[particle identification]] and [[momentum measurement]], among other things. The tracker is usually the [[subdetector]] that is closest to the [[interaction point]], where the [[Collision|collisions]] happen. In its design, the use of high-density materials is kept to a minimum to disturb the paths of the particles as little as possible and prevent [[energy loss]] of the particles via interaction with the tracker material.
