Abstract

Compact accelerator-driven neutron sources allow to operate multiple optimised target-moderator-reflector (TMR) units adapted to the requirements of the respective instruments. The compact design of the TMR units allows an efficient coupling of neutron production, neutron moderation and extraction, but requires a novel way of optimisation. The neutronic performance of different TMR units based on polyethylene, heavy water and a mixture of heavy and light water moderators together with Pb and Be reflectors and a borated polyethylene absorber is discussed. Extraction channels for thermal and cold neutrons are investigated regarding the energy and time spectra.

通过目标慢化剂反射器优化定制中子束特性
紧凑的加速器驱动中子源允许操作多个优化的目标慢化剂反射器(TMR)单元,以适应各自仪器的要求。TMR装置的紧凑设计允许中子产生、中子调节和提取的有效耦合,但需要一种新颖的优化方式。讨论了基于聚乙烯、重水和重水和轻水调节剂的混合物以及Pb和Be反射器和硼化聚乙烯吸收器的不同TMR单元的中子性能。研究了热中子和冷中子的提取通道的能量谱和时间谱。

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.
