A neutron detector that is insensitive to attendant γ rays

A neutron detector is described, whose operating principle is based on detecting charge-transfer effects of secondary recoil protons produced in hydrogen-containing materials under exposure to primary neutrons. The physical mechanism of the operation of this detector is presented and its sensitivity...

Description
Summary:A neutron detector is described, whose operating principle is based on detecting charge-transfer effects of secondary recoil protons produced in hydrogen-containing materials under exposure to primary neutrons. The physical mechanism of the operation of this detector is presented and its sensitivity is determined as a function of the neutron energy. The design of a detector that is insensitive to attendant γ rays is proposed. The serviceability of the detector has been confirmed experimentally. The detector may find application to tests in mixed fields of γ rays and neutrons.
