Abstract

A sample-motion-synchronized neutron stroboscope is developed using the RIKEN accelerator-based compact neutron source (RANS). When a sample reaches a specified rotation phase, a phase timing signal is generated, triggering a proton pulse at the proton accelerator. A neutron pulse exposes the imaging detector through the sample. By controlling the delay time between the phase signal and the proton pulse timing, the neutron exposure timing is always synchronized with the specific sample rotation phase. A sample rotating at a speed of 1800 RPM is prepared, and clear still images of neutrons are taken.

RANS的样品运动同步中子频闪仪

利用基于RIKEN加速器的紧凑型中子源（RANS）开发了一种样品运动同步中子频闪仪。当样品达到指定的旋转相位时，产生相位计时信号，触发质子加速器处的质子脉冲。中子脉冲通过样品暴露成像探测器。通过控制相位信号和质子脉冲定时之间的延迟时间，中子暴露定时总是与特定的样品旋转相位同步。准备以1800RPM的速度旋转的样品，并拍摄中子的清晰静止图像。

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.
