论文摘要
在本文中,我们提出了一种通过激活im屈箔的激活来获取具有商业化架子(COTS)CMOS图像传感器的中子图像的方法。该检测方法专门设计用于在具有高γ通量的混合梁中获取热和表级中子图像,也用于研究通常放入研究反应器池中的高放射性样品。我们还提出了一种技术,可以利用在热能范围以及1.45 eV共振范围内,利用该材料的高中子吸收横截面。在阿根廷Bariloche的RA6核研究反应堆的中子束中进行的测量结果证实了该技术的能力。
In this paper we present a method for obtention of neutron images with Commercial-Off-The-Shelf (COTS) CMOS image sensors through the activation of indium foils. This detection method has been designed specifically for the acquisition of thermal and epitermal neutron images in mixed beams with a high gamma flux, and also for the study of high radioactive samples that are usually placed into research reactor pools. We also present a technique to obtain multi-spectral neutron images taking advantage of the high neutron absorption cross-section of this material in the thermal energy range, as well as around the 1.45 eV resonance. Measurements performed in a neutron beam of the RA6 nuclear research reactor located in Bariloche, Argentina, confirm the capability of the proposed technique.
