Inelastic scattering technic for measuring the time spectrum of fusion pulse neutron source

A technic for measuring the time spectrum of high non-monoenergetic pulse neutrons induced by D-T fusion reaction was introduced-inelastic scattering convert technic. BeO was used as converter and set near the pulse neutrons source. The high energy pulse neutrons react with 16O by inelastic scattering (n, n'γ), and (is emitted in the reaction. Through measuring the time spectrum of (radiation emitted can obtain the time spectrum of D-T pulse neutrons.
