Abstract

Canada’s access to neutron beams for neutron scattering was significantly curtailed in 2018 with the closure of the National Research Universal (NRU) reactor in Chalk River, Ontario, Canada. New sources are needed for the long-term; otherwise, access will only become harder as the global supply shrinks. Compact Accelerator-based Neutron Sources (CANS) offer the possibility of an intense source of neutrons with a capital cost significantly lower than spallation sources. In this paper, we propose a CANS for Canada. The proposal is staged with the first stage offering a medium neutron flux, linear accelerator-based approach for neutron scattering that is also coupled with a boron neutron capture therapy (BNCT) station and a positron emission tomography (PET) isotope production station. The first stage will serve as a prototype for a second stage: a higher brightness, higher cost facility that could be viewed as a national centre for neutron applications.

加拿大紧凑型加速器中子源(CANS)原型

2018年，随着加拿大安大略省查尔克河国家研究通用公司（NRU）反应堆的关闭，加拿大获得中子束进行中子散射的机会大幅减少。长期而言，需要新的资源；否则，随着全球供应的萎缩，获取只会变得更加困难。基于紧凑加速器的中子源（CANS）提供了强中子源的可能性，其资本成本显著低于散裂源。在本文中，我们为加拿大提出了一个CANS。该提案分阶段进行，第一阶段提供了一种中等中子通量、基于线性加速器的中子散射方法，该方法还与硼中子捕获治疗（BNCT）站和正电子发射断层扫描（PET）同位素生产站相结合。第一级将作为第二级的原型：一个亮度更高、成本更高的设施，可以被视为中子应用的国家中心。

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.
