Abstract

This paper presents the first determination of the improvement in beam divergence when including the ANET Compact Neutron Collimator on an existing thermal neutron beam, obtained with a measuring campaign at the LENA Mark-II TRIGA reactor in Pavia. This novel collimator consists of a sequence of collimating and absorbing channels organised in a chessboard-like geometry. It has a scalable structure both in length and in the field of view. It is characterized by an elevated collimation power within a limited length. Its scalability and compactness are added values with respect to traditional collimating system. The prototype tested in this article is composed of 4 concatenated stages, each 100 mm long, with a channel width of 2.5 mm, delivering a nominal L/D factor of 160. This measuring campaign illustrates the use of the ANET collimator and its potential application in ne
紧凑中子准直器首次ANET分辨运动的实验结果
本文首次确定了在现有热中子束上安装ANET紧凑型中子准直器后,束散度的改善,这是在帕维亚的LENA Mark-II TRIGA反应堆上进行的测量活动中获得的。这种新型准直器由一系列以棋盘状几何结构组织的准直和吸收通道组成。它在长度和视野上都具有可伸缩的结构。它的特点是在有限的长度内具有较高的准直能力。它的可扩展性和紧凑性是传统准直系统的优点。本文测试的原型由4个串联级组成,每个级长100毫米,通道宽度为2.5毫米,标称L/D因子为160。这次测量活动说明了ANET准直器的使用及其在ne中的潜在应用

期刊介绍: Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
