多探测器快中子飞行时间谱仪

  • 摘要: 描述了一台串列加速器HI-13上的多探测器快中子飞行时间谱仪,并与国际上同类谱仪进行了比较。本谱仪主要用于能量大于8 MeV的快中子散射实验、次级中子双微分截面及带电粒子引起的出射中子能谱的测量。简要介绍了谱仪各主要部分(包括零信号拾取筒、氘气体靶、探测器、电子学等)的结构和特性及其在快中子实验中的应用。

     

    Abstract: A multi-detector fast neutron time of flight spectrometer is built at HI-13 tandem accelerator and compared with existing ones. The spectrometer will be used for measurements of fast neutron scattering angular distributions and double differential cross sections of secondary neutrons as well as charged particle induced neutron emission spectrum study. Main parts of the spectrometer (including beam pick-off system, deuterium gas target, neutron detector and electronics) are described briefly. The performance of the spectrometer and some applications in fast neutron experiment are also depicted.
