摘要

McStas ScatterLogger组件束适用于评估在镜面反射下超镜导膜中伴随中子捕获的快速伽马辐射对中子导膜周围剂量率的贡献。现在可以通过在McStas中运行仪器的光线追踪模拟来直接评估将这种贡献降低到所需水平所需的典型屏蔽材料的厚度。概述了对现有McStas组件的相应修改，并对新编写的补充组件进行了描述，同时给出了示例和使用说明。

McStas and Scatter Logger driven calculations of prompt gamma shielding for neutron guides

McStas ScatterLogger component bundle was adapted for evaluating a contribution to dose rate around neutron guides arising from prompt gamma radiation accompanying neutron capture in the supermirror guide coating upon specular reflection. Thickness of typical shielding materials needed to reduce this contribution to the desired level can be now evaluated directly from running a ray-tracing simulation of the instrument in McStas. An overview of the corresponding modifications to the existing McStas components and description of the newly written supplementary ones is given together with examples and use instructions.

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.
