anticoincidence
- noun
- /ˌæntiˌkɔɪnˈsɪdəns/
- Specialized
- As the charged particle intensity in space is several thousand times that of the gamma rays from cosmic sources, it would overwhelm the instrument were it not for the anticoincidence shield, which detects the presence of charged particles and signals that they are not valid gamma-ray events.
Examples
-
All four instruments have a plastic outer particle detector, called an anticoincidence counter, that records cosmic rays and other charged particles by giving off a signal different from that produced by gamma rays.
Academic text (1990) -
To reduce false signals, the device incorporated an anticoincidence feature that filtered out background noise.
-
There will also be anticoincidence vetoes to weed out environmental effects.
Academic text (1999) -
The scientist used an anticoincidence method to ensure that only simultaneous events were detected.
-
By employing an anticoincidence system, the researchers could focus on accurate measurements without interference from other particles.

Morphology
anticoincidence = coincidence (semi-transparent) = anti + coincide + ence
The form is a regular prefixation of anti- to coincidence, but the technical science/electronics sense is specialized and not fully predictable for an average learner.
Etymology
Anticoincidence is made of anti- meaning 'against' and coincidence meaning 'a happening at the same time', like in the word coincide. So, an anticoincidence method 'fights against' events that do not line up in time and blocks or filters those unwanted signals to reduce background noise.
