System and method for detecting neutrons, gamma rays, and mu mesons using adjacent plastic scintillators

摘要

A radiation detecting system, including: plastics scintillators juxtaposed to form at least one pair of contiguous plastics scintillators; a photomultiplier associated with each plastics scintillator to provide an electrical signal representative of the light signal generated in the plastics scintillator; a calculator connected to the photomultipliers and configured to: detect pulse coincidences between two electrical pulses provided by the photomultipliers associated with a pair of contiguous plastics scintillators; for each pulse coincidence, determine the time offset between the coincidence pulses relative to the pulse having the greatest amplitude taken as a zero reference; determine the number of pulse coincidences the time offset of which is included in a time offset window.
