我们研制了一种混合粉末中子闪烁体作为一种新型的中子探测材料。由于LiF-Ag:ZnS混合粉末是广泛使用的混合粉末中子闪烁体,由于Ag:ZnS的极高折射率而不透明,因此闪烁体厚度受到限制。本文提出采用LiF和Eu:CaF_2具有几乎相同折射率的LiF-Eu:CaF_2混合粉末作为大致透明的混合粉末中子闪烁体。虽然刚混合的LiF-Eu:CaF 2粉末是不透明的,但通过用液体玻璃树脂作为折射率缓冲物填充粉末中的间隙差距,它可以变得半透明。结果表明,在LiF-Eu:CaF_2混合粉末闪烁体辐照热中子时,在脉冲高度谱中观察到一个峰形。
We developed a mixed powder neutron scintillator as a novel neutron detection material. Since LiF-Ag:ZnS mixed powder, which is a widely used mixed powder neutron scintillator, is opaque owing to the extremely high refractive index of Ag:ZnS, the scintillator thickness is limited. We proposed the use of LiF-Eu:CaF2mixed powder, where both LiF and Eu:CaF2have almost the same refractive index, as a roughly transparent mixed powder neutron scintillator. Although the just mixed LiF-Eu:CaF2powder is opaque, it can become translucent by filling the gap in the powder with a liquid glass resin as a refractive index buffer. As a result, we observe a peak shape in the pulse height spectrum obtained from the LiF-Eu:CaF2mixed powder scintillator when irradiating thermal neutrons.
