It uses state of the art coincidence circuits to eliminate any false alarms.

Many counters have two photo multiplier tubes connected in a coincidence circuit.

The coincidence circuit assures that genuine light pulses are counted.

The Rossi coincidence circuit was rapidly adopted by experimenters around the world.

The method involves a triggerable oscillator and a coincidence circuit.

In physics, a coincidence circuit is an electronic device with one output and two (or more) inputs.

They are connected in a coincidence circuit.

Short decay times are important for the measurement of time intervals and for the operation in fast coincidence circuits.

Known as the Rossi coincidence circuit, it recorded the simultaneous occurrence of three or more electrical pulses.

Coincidence circuits are widely used in particle physics experiments and in other areas of science and technology.

Bruno Rossi invented the electronic coincidence circuit for implementing the coincidence method.

Both detectors are connected to a coincidence circuit, ensuring that only entangled photon pairs are counted.

The Rossi coincidence circuit has two major advantages: it offers very precise temporal resolution and it can detect coincidences among any number of pulse sources.

Within a few weeks of reading his paper with Kolhörster, Rossi invented an improved electronic coincidence circuit, which made use of triode vacuum tubes.

In this configuration, the frequency of coincidences was greater than that calculated on the basis of the individual rates and the resolving time of the coincidence circuit.

This is true, regardless of whether the device was used for communication (i.e. sans coincidence circuit), or not (i.e. in coincidence).

Hence, more events are rejected by the coincidence circuit and the height of the pulse height spectrum is suppressed, often without a particularly noticeable shift of the spectrum.

Walther Bothe, inventor of the coincidence circuit, got part of the 1954 Nobel Prize in physics, for the first modern electronic AND gate in 1924.

To study them, he invented an improved electronic coincidence circuit, and travelled to Eritrea to conduct experiments that showed that cosmic ray intensity from the West was significantly larger than that from the East.

The coincidence circuit assures that genuine light pulses, which reach both photomultiplier tubes, are counted, while spurious pulses (due to line noise, for example), which would only affect one of the tubes, are ignored.

To detect the voltage pulse produced by the coincidence circuit when a coincidence event occurred, Rossi first used earphones and counted the 'clicks', and soon an electro-mechanical register to count the coincidence pulses automatically.

If such a system is pointed toward a cloud and lightning occurs in that cloud, both signals will be received; the coincidence circuit will produce an output; and the user can be sure the cause was lightning.

With Occhialini's help in the construction of GM tubes, and with the aid of a practical coincidence circuit, Rossi confirmed and extended the results of Bothe, who invited him to visit Berlin in the summer of 1930.

However, since RF signals and light pulses rarely occur simultaneously except when produced by lightning, RF sensors and light pulse sensors can usefully be connected in a "coincidence circuit" which requires both kinds of signals simultaneously in order to produce an output.

The circuit performs this function by feeding the output at the Bat position (pin 9 on IC2) to one of the inputs, via diode D13, of a discrete coincidence gate made up from transistors TR3 and TR4.
