DEVICE FOR DETECTING FAST NEUTRONS Russian patent published in 2010 - IPC G01T3/06 

FIELD: physics.

SUBSTANCE: signal processing circuit includes the following: amplitude discriminators, coincidence circuits, a signal adder and an amplitude analyser. Plates of the organic scintillator have different thickness. Thickness of the receiving plate and is equal to half the path of the most energetic recoil proton and thickness of the bottom plate is equal to the path of the most energetic recoil proton. The plates are separated by opaque material. The outer side of both plates is coated with light-reflecting material and then with opaque material.

EFFECT: increased efficiency and reliability of detecting neutrons with different energies, cheaper and simpler design of the detector.
