In particle physics experiments, several sets of identical detecting planes are commonly used in parallel to achieve greater efficiencies than is possible using single planes. Instead of observing whether or not a single plane fires, which may be erroneously caused by random background noise, a combination of feedback from multiple detecting planes is considered. By setting up appropriate criteria (such as taking a lower bound of simultaneous firings of the planes to be an effective event), it is possible to reach very high efficiencies. From the number of detecting planes and a proposed judging criterion, this Demonstration calculates the total inefficiency from a given individual plane's efficiency. This is shown on a graph of total inefficiency as a function of individual plane efficiency, assuming all the individual planes have equal efficiencies.
