摘要
介绍DT聚变反应产生的非单能的高能脉冲中子时间谱的一种测量技术——非弹散射法。利用安装在脉冲中子源附近的氧化铍(BeO)材料作为辐射转换体,测量DT聚变反应产生的高能脉冲中子与16O的非弹散射(n,n′γ)过程中产生的γ辐射时间谱,实现对DT反应脉冲中子时间谱的测量。
<Abstrcat> 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 ()^(16)O 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.
