摘要：利用Geant4代码对新n_TOF-EAR2设施的中子束特性进行了模拟，旨在为即将进行的测量的分析和规划提供有用的数据。中子的空间和能量分布、分辨率函数和束内伽马射线背景已经被详细研究，并讨论了它们在即将进行的实验中的含义。结果证实，凭借这条新的短（18.5m 飞行路径）束线，在 keV 区域达到超过 105n/μs/脉冲的瞬时中子通量，n_TOF 是少数可以进行具有挑战性测量的设施之一，特别是涉及短寿命放射性同位素。
Abstract.The characteristics of the neutron beam at the new n_TOF-EAR2 facility have been simulated with the Geant4 code with the aim of providing useful data for both the analysis and planning of the upcoming measurements. The spatial and energy distributions of the neutrons, the resolution function and the in-beam $ \gamma$-ray background have been studied in detail and their implications in the forthcoming experiments have been discussed. The results confirm that, with this new short (18.5m flight path) beam line, reaching an instantaneous neutron flux beyond 105n/μs/pulse in the keV region, n_TOF is one of the few facilities where challenging measurements can be performed, involving in particular short-lived radioisotopes.
