Abstract

An approach for the measurement of the number of high-energy pulsed fission neutrons is investigated. The radiation absorber in the beam and the thickness of CH ₂ proton radiator are optimized. The background from scattering neutrons and gamma rays is measured in situ using the back-to-back structure designed and then subtracted directly. The signal-to-background ratio of the detection system for measuring high-energy fission neutrons is up to 10.
