摘要

巴黎-爱丁堡（PE）压机是目前用于10GPa及以上范围中子散射的主要高压设备。在这里，我们介绍了垫圈砧座组件的发展，与目前使用的“单环面”砧座相比，该组件的压力性能提高了30%，使用寿命显著延长，但仍给出了类似的信号与背景比。我们还提供了一种改进的Bridgman密封包装，使PE压机的低温运行更加可靠。报道了对“赤道”散射几何中背景源的系统研究。

Advances in the use of Paris-Edinburgh presses for high pressure neutron scattering

Paris-Edinburgh (PE) presses are nowadays the dominant high pressure devices for neutron scattering in the 10 GPa range and above. Here, we present developments of gasket-anvil assemblies with 30% improved pressure performance and considerably increased lifetime compared to the currently used “single-toroidal” anvils, and giving nevertheless a similar signal-to-background ratio. We also present an improved Bridgman seal package which makes the low-temperature operation of the PE press significantly more reliable. A systematic investigation of background sources in the “equatorial” scattering geometry is reported.

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.
