论文摘要
GN-Vision是一种新颖的双$γ$ ray和中子成像系统,旨在同时获得有关$γ$ ray和中子源的空间起源的信息。所提出的设备基于两个位置敏感检测平面,并利用Compton成像技术来成像$γ$ -RASE。此外,通过使用连接到第一个检测平面的被动中子孔孔直接仪,可以重建慢速和热中子源($ <$ 100 eV)的空间分布($ <$ 100 eV)。拟议的伽马西亚成像设备可能是核安全和安全应用的主要兴趣。该成像系统的两个主要优点是其高效率和便携性,使其非常适合核应用是紧凑性,实时成像很重要。这项工作介绍了基于Monte Carlo模拟的GN-Vision系统的工作原理和概念设计,并探讨了其同时$γ$ ray和中子检测和成像功能,以实现安全检查的现实情况,其中$^{252} $ CF源隐藏在中子的调整容器中。
GN-Vision is a novel dual $γ$-ray and neutron imaging system, which aims at simultaneously obtaining information about the spatial origin of $γ$-ray and neutron sources. The proposed device is based on two position sensitive detection planes and exploits the Compton imaging technique for the imaging of $γ$-rays. In addition, spatial distributions of slow- and thermal-neutron sources ($<$100 eV) are reconstructed by using a passive neutron pin-hole collimator attached to the first detection plane. The proposed gamma-neutron imaging device could be of prime interest for nuclear safety and security applications. The two main advantages of this imaging system are its high efficiency and portability, making it well suited for nuclear applications were compactness and real-time imaging is important. This work presents the working principle and conceptual design of the GN-Vision system based on Monte Carlo simulations and explores its simultaneous $γ$-ray and neutron detection and imaging capabilities for a realistic case of a security inspection where a $^{252}$Cf source is hidden in a neutron moderating container.
