On the possibility of separating signals of pulsed ionization detectors from amplifier noise by using self-coincidences

A method for separating ionization detector pulses from amplifier noise is proposed. Two amplifiers are used. As usual, one amplifies the signal from the detector anode, while the other amplifies the signal from the cathode. Summing the signals, we obtain the total noise of both amplifiers during a pulse. Knowing the noise distribution law for each channel, we divide the noise sum integral by pairs of the noise integrals in the channels with an estimate of their probability. Subtracting the noise integral from the channel signal integral, we obtain possible values for the detector pulses with an indicator of their probabilities. A regime for continuous signal analysis without use of the coincidence scheme is also proposed.
