anti-coincidence
anti-coˈincidence Physics. [f. anti-1 4 + coincidence 7.] Applied attrib. to a device, or to a system employing a device, which rejects or discriminates against measurements of events which occur simultaneously or are separated by a predetermined time, used esp. in experiments with cosmic rays and i...

Electronic anticoincidence
The main detector and the suppression detector are run in anti-coincidence, which means that if they both detect a gamma ray then the gamma ray has scattered

Anti-coincidence
The anti-coincidence method, similarly to the coincidence However, anti-coincidence designs are used to actively reject non-signal particles rather than affirm signal particles.

OSO 3
Sail carried a hard X-ray experiment from UCSD, with a single thin NaI(Tl) scintillation crystal plus phototube enclosed in a howitzer-shaped CsI(Tl) anti-coincidence

OSO 7
Edward Chupp, observed 0.3–10 MeV solar flare gamma rays with a NaI(Tl) scintillation spectrometer in a CsI(Na) active anti-coincidence shield. The detector was enclosed in a thick CsI(Na) anti-coincidence scintillation shield with 10 holes bored through it, which defined the optical field of view

Energetic Gamma Ray Experiment Telescope
To accomplish its task, EGRET was equipped with a spark chamber, calorimeter, and plastic scintillator anti-coincidence dome. Starting from the outside of the telescope, scientists covered EGRET with a plastic scintillator anti-coincidence dome.
