Coincidence designs are an essential technique for increasing confidence in signals and reducing random background within a wide range of particle detectors. Common backgrounds include radioactive decay products (beta, alpha, and gamma radiation) and cosmic rays (protons, air showers). Such backgrounds can produce random interactions within a particle detector that may be hard to differentiate from the target particle. If the particle in question is able to trigger multiple channels that are correlated in time or space, it can be determined more likely that the particle is not a background trigger. "Chance" coincidence events may occur, in which all channels are triggered by particles which are not under investigation yet happen to interact with each channel at the same time. In this case, measurements of this chance event may be difficult to separate from measurements of the target events.
