摘要

iphi -中子设备是一个低能中子can (E p = 3 MeV)，用于测试用于构建大电流can (HiCANS)的各种技术。研究计划的一部分包括研究在can周围进行中子散射和射线照相实验的可能性。为此，最近在IPHI源周围安装了DIoGENE仪器。该仪器的目的是作为一个通用的中子散射仪器，具有256个高压3氦管，覆盖0.74 sr的立体角。该仪器特别适合于衍射实验，但可以升级为SANS或反射仪。我们正在使用DIoGENE仪器研究中子TMR的性能，快中子和伽马射线产生的背景噪声相关问题，以及更普遍的ToF数据采集协议和事件模式下的处理。本文介绍了新型高功率Be靶在ihi中子上的最新衍射结果。

Neutron scattering on DIoGENE at IPHI–neutrons

The IPHI–Neutrons facility is a low energy neutron CANS ( E p = 3 MeV) used to test various technologies for the construction of high current CANS (HiCANS). Part of the research program includes the investigation of the possibility to perform neutron scattering and radiography experiments around CANS. For this purpose, the DIoGENE instrument has recently been installed around the IPHI source. The instrument is aimed as a general-purpose neutron scattering instrument featuring 256 high-pressure 3 He tubes covering a solid angle of 0.74 sr. The instrument is especially suited for diffraction experiments but may be upgraded as a SANS or reflectometry instrument. We are using the DIoGENE instrument to investigate the performances of the neutron TMR, the issues related to background noise due to fast neutrons and gamma rays productions and more generally the ToF data acquisition protocols and processing in event mode. We present in this communication the recent diffraction results obtained on DIoGENE during the tests of the new high power Be target on IPHI–Neutrons.

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.
