Abstract

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 CH2 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.
