精确的中子能量测量需要探测富中子核的核结构效应,其中缓发中子发射成为主要的衰变模式。设计并建造了具有Xn跟踪(NEXT)阵列的中子探测器,以更好的能量分辨率测量缓发中子。新的设计定位的中子相互作用的位置,光学分割探测器沿着的中子飞行路径的方向,减少相关的不确定性,在中子飞行时间测量。这在不损失必要的检测效率的情况下显著提高了能量分辨率。原理验证和效率测量显示出令人鼓舞的结果。本文详细介绍了NEXT阵列在飞行时间测量中中子跟踪能力的实现。
Precise neutron-energy measurements are required to probe the nuclear structure effects of neutron-rich nuclei, where-delayed neutron emission becomes a dominant decay mode. The Neutron dEtector with Xn Tracking (NEXT) array has been designed and constructed to measure-delayed neutrons with better energy resolution. The new design localizes the neutron interaction position by optically segmenting the detector along the direction of the neutron flight path, reducing the associated uncertainties in the neutron time-of-flight measurements. This significantly improves the energy resolution without losing the necessary detection efficiency. The proof-of-principle and efficiency measurements showed promising results. This article details the implementation of the neutron tracking capability of NEXT array in time-of-flight measurements.
