在这项工作中，我们表征了直径为 1 英寸、高度为 1 英寸的圆柱形无机 Cs 2 LiYCl 6: Ce 探测器的 γ 射线响应和效率。能量分辨率和线性度是从能量范围为 0.026 至 2.447 MeV 的 21 条 γ 射线获得的。此外，通过测量 252 Cf 放射性同位素来验证中子 γ 射线辨别能力。使用蒙特卡罗方法模拟 7 MeV 以下的伽马射线响应函数和矩阵，并通过展开的伽马射线光谱进行验证。
In this work, we characterize the γ-ray response and efficiency for a cylindrical inorganic Cs 2 LiYCl 6: Ce detector 1′′ in diameter and 1′′ in height. The energy resolution and linearity are obtained from 21 γ-rays with energies ranging from 0.026 to 2.447 MeV. In addition, the neutron γ-ray discrimination is validated by measuring a 252 Cf radioisotope. Gamma-ray response functions and matrix below 7 MeV are simulated using a Monte Carlo approach and validated through the unfolded γ-ray spectra.
